Product details
Overview
MAX5007BEUB from Maxim Integrated is a 3.3V, 150mA low-dropout linear voltage regulator with integrated USB D+/D− transient voltage suppression (±15kV), precision 1.5kΩ data-line termination resistors, and an active-high push-pull reset output. It delivers regulated power to USB microcontrollers while protecting data lines and asserting reset 100ms after VOUT reaches regulation-used in USB peripheral power management.
For engineers reviewing the MAX5007BEUB datasheet, MAX5007BEUB pinout, MAX5007BEUB application, or MAX5007BEUB equivalent, key selection criteria include its fixed 3.3V ±3% output, 25µA quiescent current at full load, 10-pin µMAX package, ±15kV ESD protection on D+/D−, and active-high reset timing behavior under brownout and manual reset conditions.
Technical Context
The MAX5007BEUB integrates an LDO regulator, USB data-line TVS clamping circuitry, selectable 1.5kΩ termination (via SELR/ENR), and a precision reset supervisor sharing the same bandgap reference. Its reset threshold is factory-set to −12.5% of nominal VOUT (2.89V typical), with 100ms minimum timeout and <75µs VOUT-to-reset delay.
It features output-to-input reverse leakage protection, thermal shutdown at +160°C with 20°C hysteresis, short-circuit current limiting (165–350mA), and stable operation with only 1µF ceramic output capacitance-optimized for space-constrained USB peripheral designs requiring robust signal integrity and power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3V ±3% - ensures reliable USB controller biasing across temperature and load. |
| Max Load Current | 150mA - sufficient for USB full-speed peripherals including hubs and HID devices. |
| Dropout Voltage | 400mV max at 150mA - enables operation from 4.0V–5.5V input, compatible with USB VBUS tolerance. |
| Quiescent Current | 25µA at full load - minimizes standby power loss in battery-backed or portable USB devices. |
| Reset Threshold | 2.75V to 3.01V (B-grade) - triggers reset when VOUT drops >12.5% below nominal, preventing logic faults. |
| D+/D− ESD Rating | ±15kV air discharge - meets IEC 61000-4-2 Level 4 for robust field deployment in consumer USB ports. |
| Termination Resistor | 1.5kΩ ±5% - matches USB full-/low-speed impedance requirements without external components. |
Pinout & Package
MAX5007BEUB is housed in a 10-pin µMAX package (3mm × 3mm, 0.8mm height), thermally enhanced with dual GND pins (pins 3 and 9) serving as heatsinks. The package requires soldering to large copper areas for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Regulator input | Accepts 4.0V–5.5V USB VBUS; bypassed with 1µF ceramic capacitor to GND for stability. |
| 2 D+ | USB D+ data line interface | Integrated ±15kV TVS; connects to 1.5kΩ termination resistor when SELR=HIGH & ENR=LOW. |
| 3,9 GND | Ground / thermal pad | Common return path and primary heat dissipation node; must connect to PCB ground plane. |
| 4 D− | USB D− data line interface | Integrated ±15kV TVS; connects to 1.5kΩ termination resistor when SELR=LOW & ENR=LOW. |
| 5 SELR | Termination select control | Logic HIGH selects D+ termination (full-speed); LOW selects D− termination (low-speed). |
| 6 ENR | Termination enable control | LOW enables selected 1.5kΩ resistor; HIGH or asserted reset disables termination. |
| 7 RESET | Active-high reset output | Push-pull driver asserts HIGH during power-up/brownout/manual reset; remains HIGH ≥100ms after recovery. |
| 8 MR | Manual reset input | Active-low; internal 25kΩ pullup to OUT; debounced by design-no external RC needed. |
| 10 OUT | Regulated 3.3V output | Sources up to 150mA; requires ≥1µF ceramic capacitor; reverse-leakage protected from IN. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated ±15kV D+/D− TVS | Eliminates need for discrete ESD diodes; complies with IEC 61000-4-2 Air Discharge Level 4. |
| Pin-selectable 1.5kΩ termination | Configures USB full-speed (D+) or low-speed (D−) termination via SELR/ENR logic-no BOM change required. |
| Active-high push-pull RESET | Directly drives CMOS inputs without external pullup; eliminates race conditions in reset-sensitive USB controllers. |
| Output-to-input reverse leakage protection | Prevents backfeed from auxiliary supplies (e.g., backup battery) into VBUS-no external blocking diode needed. |
| Thermal & short-circuit protection | Shuts down at +160°C junction temp; recovers after 20°C cooldown-enables indefinite short-circuit survival. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX5006BEUB | Active-low push-pull RESET output; identical LDO, TVS, and termination specs. | Requires inverted reset logic on host MCU; unsuitable where active-high reset is mandated by firmware. | Select MAX5006BEUB only if system design expects active-low reset assertion and no level-shifting is feasible. |
| TUSB2036IPWR | USB 2.0 hub controller with integrated 3.3V LDO (100mA), no D+/D− TVS or reset circuit. | Lacks ±15kV ESD protection and independent reset supervision-requires external TVS and reset IC. | Choose TUSB2036IPWR only for multi-port hub applications where integrated PHY and packet routing outweigh discrete protection needs. |
Compared with MAX5006BEUB, MAX5007BEUB provides native active-high reset compatibility with modern USB controllers; compared with TUSB2036IPWR, it offers complete single-chip USB power + protection + reset functionality at lower BOM cost and smaller footprint-ideal for single-peripheral designs.

FAQ
What is the reset behavior of the MAX5007BEUB during power-up?
The MAX5007BEUB asserts its active-high RESET output for a minimum of 100ms after the 3.3V output reaches regulation. This ensures the connected USB microcontroller completes power stabilization before release. The reset timeout is guaranteed over temperature and load, and the MAX5007BEUB's internal supervisor uses the same reference as the LDO for tight tracking-preventing premature release due to VOUT droop during startup.
How does the MAX5007BEUB protect USB D+ and D− lines from ESD events?
The MAX5007BEUB integrates proprietary shunt-type TVS structures on both D+ and D− pins, rated for ±15kV air-gap discharge per IEC 61000-4-2 Level 4. Unlike series protection, this architecture introduces no signal delay or impedance mismatch. The MAX5007BEUB achieves this with <1µA leakage and ~40pF capacitance at 1MHz-preserving USB signal integrity while eliminating external ESD diodes.
Can the MAX5007BEUB be used with a 10µF output capacitor?
Yes-the MAX5007BEUB remains stable with output capacitors up to 10µF, and larger values improve load transient response and PSRR. The datasheet confirms stability with 1µF (minimum), 2.2µF (typical test condition), and 10µF (shown in load transient plots). Using 10µF reduces output voltage deviation during 20mA step loads to <50mV, making the MAX5007BEUB suitable for noise-sensitive USB PHYs and ADCs.
What is the function of the SELR and ENR pins on the MAX5007BEUB?
SELR and ENR configure USB termination: SELR selects D+ (HIGH) or D− (LOW) for full- or low-speed mode; ENR enables (LOW) or disables (HIGH) the 1.5kΩ resistor. When RESET is asserted, termination is automatically disabled. This allows dynamic speed negotiation in firmware-controlled USB devices-no hardware changes needed. The MAX5007BEUB's internal logic ensures glitch-free switching between modes without affecting D+/D− signal integrity.
Does the MAX5007BEUB support reverse power flow from OUT to IN?
No-the MAX5007BEUB includes dedicated output-to-input reverse leakage protection that actively blocks current flow from OUT to IN. When VOUT exceeds VIN, internal circuitry disables the pass transistor and parasitic paths, ensuring zero reverse conduction. This allows safe use of backup batteries or auxiliary supplies on the OUT rail without external diodes-verified across −40°C to +85°C and confirmed in the MAX5007BEUB's Absolute Maximum Ratings table.
