Product details
Overview
MAX5007AEUB from Maxim Integrated is a 3.3V, 150mA low-dropout (LDO) linear voltage regulator with integrated USB D+/D− transient voltage suppression (±15kV IEC 1000-4-2 air discharge), precision 1.5kΩ data-line termination resistors, and an active-high push-pull reset output. It delivers regulated power and supervisory functions for USB peripheral devices operating from a 4.0V–5.5V input, featuring 25µA quiescent current and thermal/short-circuit protection.
For engineers reviewing the MAX5007AEUB datasheet, MAX5007AEUB pinout, MAX5007AEUB application, or MAX5007AEUB equivalent, this device is selected for USB-powered peripherals requiring simultaneous LDO regulation, ESD-hardened data-line interface, and deterministic µP reset timing with active-high assertion-especially where manual reset, reverse leakage protection, and 1µF ceramic capacitor stability are critical.
Technical Context
The MAX5007AEUB integrates a BiCMOS LDO core with a dedicated reset supervisor using the same bandgap reference as the regulator, ensuring correlated threshold tracking across temperature. Its reset circuit asserts high when VOUT falls below a −7.5% threshold (3.05V typical) and sustains the signal for ≥100ms after recovery.
USB data-line protection is implemented via shunt-type TVS diodes directly on D+ and D− pins, delivering ±15kV air-discharge ESD immunity without signal delay or series impedance. Termination resistors are enabled via dual logic inputs (SELR and ENR), allowing dynamic selection between full-speed (D+ to OUT) and low-speed (D− to OUT) configurations under software or hardware control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±3% - ensures stable USB VCC rail compliance across load and temperature. |
| Max Output Current | 150mA - sufficient for USB full-speed peripherals including microcontrollers and transceivers. |
| Dropout Voltage | 400mV max at 150mA - enables operation down to 3.7V input while maintaining regulation. |
| Reset Threshold | 3.05V (−7.5% of 3.3V) - triggers active-high RESET when output drops out of spec, supporting reliable µP initialization. |
| Quiescent Current | 25µA at full load - minimizes standby power in battery-backed or energy-sensitive USB accessories. |
| D+/D− TVS Rating | ±15kV air discharge (IEC 61000-4-2) - eliminates need for external ESD protection diodes on USB data lines. |
| Termination Resistor | 1.5kΩ ±5% - matches USB specification for full-speed (12Mbps) and low-speed (1.5Mbps) termination without external components. |
Pinout & Package
MAX5007AEUB is housed in a 10-pin µMAX package (3mm × 3mm, 0.5mm pitch), with exposed pad for thermal dissipation. GND pins (3 and 9) serve dual roles as electrical ground and heatsink-must be soldered to large PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator Input | Accepts 4.0V–5.5V USB VBUS; requires 1µF ceramic bypass to GND for stability. |
| 2 D+ | USB D+ Data Line Interface | ESD-protected I/O; connects to host/device D+; termination enabled via SELR/ENR logic. |
| 3,9 GND | Power & Thermal Ground | Primary return path and thermal conduction path; must be tied to PCB ground plane. |
| 4 D− | USB D− Data Line Interface | ESD-protected I/O; connects to host/device D−; termination enabled via SELR/ENR logic. |
| 5 SELR | Termination Select Control | Logic high routes 1.5kΩ resistor from D+ to OUT (full-speed); low routes from D− to OUT (low-speed). |
| 6 - | Not connected (NC) | No internal connection; leave unconnected per datasheet. |
| 7 RESET | Active-High Reset Output | Push-pull output asserted high during power-up/brownout; remains high ≥100ms after VOUT recovery. |
| 8 MR | Manual Reset Input | Active-low input with 25kΩ internal pullup to OUT; initiates reset when pulled to GND. |
| 10 OUT | Regulated Output | 3.3V fixed output sourcing up to 150mA; bypass with ≥1µF ceramic capacitor for full performance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated ±15kV D+/D− TVS | Meets IEC 61000-4-2 Level 4 air discharge without external components-reduces BOM count and PCB footprint. |
| Pin-selectable 1.5kΩ termination | Configurable full-speed/low-speed USB termination via SELR/ENR logic-enables single design to support multiple USB speeds. |
| Active-high push-pull RESET | Eliminates need for external pullup resistor; drives µP reset directly with defined voltage levels and timing. |
| Output-to-input reverse leakage protection | Blocks current flow from OUT to IN when VOUT > VIN-allows safe backup battery operation without external diodes. |
| Thermal & short-circuit protection | Shuts down pass transistor above +160°C junction temp and limits output current to ~350mA-ensures robustness in fault conditions. |
Applications
| USB Peripheral Power Management | Hand-Held Instrumentation |

IC Role / Device Role / Timing Role: Provides regulated 3.3V VCC, terminates D+/D−, suppresses ±15kV transients, and asserts active-high reset to initialize MCU upon power-up. Use Value: Eliminates 4–6 discrete components (LDO, TVS diodes, termination resistors, reset IC), reducing layout area by >30% and improving system-level ESD reliability. | Use Scenario: Battery-powered handheld test equipment with USB connectivity that must survive repeated field ESD exposure and maintain accurate sensor biasing. IC Role / Device Role / Timing Role: Delivers stable 3.3V supply with ultra-low 25µA quiescent current, protects D+/D− against operator-induced ESD, and provides deterministic reset timing for firmware recovery. Use Value: Extends battery life in standby mode and guarantees µP reset assertion within 100ms of VOUT stabilization-critical for calibration integrity. |
| Industrial USB Adapters | Embedded USB Host Controllers |
Use Scenario: Isolating and conditioning USB signals in factory-floor adapters connecting legacy RS-232/485 devices to PC hosts. IC Role / Device Role / Timing Role: Regulates local 3.3V rail, terminates D+/D− to meet USB electrical specs, and provides active-high reset to synchronize adapter firmware startup.

IC Role / Device Role / Timing Role: Supplies clean 3.3V to USB PHY and controller, monitors VOUT for brownout detection, and asserts RESET high to hold controller in reset until stable. Use Value: Prevents spurious enumeration or enumeration failure due to marginal VOUT-reset timeout (≥100ms) exceeds USB specification's 10ms minimum. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar USB LDO regulator with reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX5006AEUB | Active-low push-pull RESET output; identical LDO, TVS, and termination specs. | Requires inverted reset logic on µP side; not suitable for systems expecting active-high assertion. | Select when host MCU reset pin is active-low and no level-shifting is desired. |
| TPS2051BDBVR | 500mA USB power switch with overcurrent protection only-no integrated TVS, termination, or reset circuitry. | Requires external TVS diodes, 1.5kΩ resistors, and separate reset IC-increases component count and board area. | Choose only if higher current (500mA) is required and system-level ESD/termination design is already handled externally. |
Compared with MAX5006AEUB, MAX5007AEUB simplifies µP interface by eliminating external inverters; compared with TPS2051BDBVR, it consolidates three functions (regulation, protection, supervision) into one die-reducing total solution size by ~45% and qualification effort for USB-compliant designs.

FAQ
What is the reset threshold voltage for MAX5007AEUB?
The MAX5007AEUB features a −7.5% reset threshold, meaning RESET asserts high when VOUT falls below 3.05V (typical) and remains high for ≥100ms after VOUT recovers above that threshold. This value is confirmed in the Electrical Characteristics table for MAX500_AEUB variants and applies specifically to the MAX5007AEUB ordering option.
Does MAX5007AEUB require external components for USB D+/D− termination?
No. MAX5007AEUB integrates two precision 1.5kΩ ±5% termination resistors internally. Selection between D+ and D− termination is controlled by the SELR and ENR logic inputs-no external resistors are needed for USB full-speed or low-speed compliance.
Can MAX5007AEUB operate with a 1µF output capacitor?
Yes. MAX5007AEUB is optimized for stability with a minimum 1µF ceramic output capacitor (X7R/X5R dielectric recommended). The datasheet confirms stable operation up to 150mA load across −40°C to +85°C using this value-no larger capacitor is required for basic functionality.
How does the ±15kV ESD protection on MAX5007AEUB work without affecting USB signal integrity?
MAX5007AEUB uses a proprietary shunt-type TVS structure directly on D+ and D− pins, which clamps transients without inserting series impedance. This preserves signal rise/fall times and adds only 40pF typical capacitance at 1MHz-well within USB full-speed requirements and avoiding data corruption or timing violations.
Is there reverse current protection between OUT and IN on MAX5007AEUB?
Yes. MAX5007AEUB includes output-to-input reverse leakage protection: when VOUT exceeds VIN, internal circuitry disables the pass transistor and parasitic paths, blocking current flow from OUT to IN. This allows safe operation with auxiliary supplies (e.g., backup batteries) without external blocking diodes.
