Product details
Overview
MAX8530EBTB2-T from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset circuit, delivering 200mA on OUT1 and 150mA on OUT2 from a 2.5V–6.5V input. It features 100mV typical dropout at 100mA, 130µA quiescent current with both LDOs active, and an open-drain active-low RESET output timed to OUT1 voltage threshold (87% nominal, ≥100ms timeout). It targets space-constrained, battery-powered systems such as cellular handsets and PDAs.
For engineers reviewing the MAX8530EBTB2-T datasheet, MAX8530EBTB2-T pinout, MAX8530EBTB2-T application, or MAX8530EBTB2-T equivalent, key selection criteria include guaranteed dual-output current capability, UCSP package footprint (1.16 × 1.57 mm), integrated reset timing without external components, and thermal/short-circuit protection for robust portable power management.
Technical Context
The MAX8530EBTB2-T integrates two independent P-channel MOSFET-based LDO regulators with internal 1.25V bandgap reference and error amplifiers. Each regulator uses internal feedback dividers to set output voltage - in this variant, OUT1 = 2.8V and OUT2 = 1.8V per Output Voltage Selector Guide (top mark ACR). The RESET block monitors OUT1 only and asserts an open-drain low signal when voltage falls below 87% of nominal, with ≥100ms timeout after recovery.
Shutdown is controlled by a single logic-input SHDN pin that reduces total supply current to <1µA. Thermal shutdown activates at +160°C junction temperature with 10°C hysteresis, and current limiting ensures minimum 210mA (OUT1) and 165mA (OUT2) trip thresholds. The device operates across –40°C to +85°C and is optimized for ceramic output capacitors ≥2.2µF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 6.5V - supports single-cell Li-ion, Li-polymer, and multi-cell alkaline/NiMH battery inputs. |
| OUT1 / OUT2 Output Current | 200mA / 150mA guaranteed - sufficient to power baseband processors and I/O rails in handheld devices. |
| Dropout Voltage (100mA) | 100mV typical - enables extended battery runtime by regulating down to VIN − 100mV. |
| Quiescent Current | 130µA with both LDOs active - minimizes standby power loss in always-on subsystems. |
| RESET Threshold Accuracy | 84% to 89% of nominal OUT1 voltage - ensures reliable microprocessor reset during brownout conditions. |
| Shutdown Current | <1µA - meets ultra-low-power requirements for sleep-mode operation. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and consumer portable equipment environments. |
Pinout & Package
MAX8530EBTB2-T is packaged in a 6-bump UCSP (1.16 × 1.57 × 0.6 mm, 3 × 2 grid), with solder bumps arranged in two rows. The package is lead-free and RoHS-compliant. Pin mapping is identical for all UCSP variants of MAX8530.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT2 (B3) | Regulator 2 output terminal | Delivers fixed 1.8V (per top mark ACR) up to 150mA; requires ≥1µF output capacitor for stability. |
| IN (B2) | Main input supply connection | Accepts 2.5V–6.5V; must be decoupled with ≥2.2µF ceramic capacitor close to the pin. |
| OUT1 (B1) | Regulator 1 output terminal | Delivers fixed 2.8V (per top mark ACR) up to 200mA; primary reset monitoring point. |
| GND (A1) | Power and signal ground reference | Serves as thermal conduction path; must connect to large PCB ground plane for thermal dissipation. |
| SHDN (A2) | Active-high shutdown control input | Logic high (≥1.6V) enables both regulators; logic low (<0.4V) disables outputs and reduces IQ to <1µA. |
| RESET (A3) | Open-drain, active-low reset output | Pulled low when OUT1 < 87% nominal or during shutdown; requires external pull-up for µP interface. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | 200mA/150mA outputs with separate internal feedback - eliminates need for discrete regulators in dual-rail systems. |
| Integrated reset generator | Monitors only OUT1 with 87% threshold and ≥100ms timeout - removes external reset IC and resistor divider. |
| P-channel MOSFET pass devices | 1Ω RDS(ON) typ - enables low dropout proportional to load, unlike fixed-VCE(sat) PNP alternatives. |
| Thermal and short-circuit protection | 160°C shutdown with 10°C hysteresis + indefinite short-circuit tolerance - ensures safe operation under fault conditions. |
| Ultra-small UCSP package | 1.16 × 1.57 mm footprint - fits into tight spaces typical of cellular phone baseband modules and wearable electronics. |
Applications
| Cellular Handset Power Management | PDAs and Palmtop Computers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO-with-reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8530ETTK2-T | Same dual-LDO + RESET functionality but in 3mm × 3mm thin QFN-EP package (6-pin); higher thermal dissipation (1951mW vs. 308mW). | Preferred where board space permits larger footprint and higher continuous power is needed (e.g., industrial handhelds). | Select MAX8530ETTK2-T if thermal performance outweighs size constraints; same electrical specs and pinout as UCSP version. |
| TPS79528DCQ | Single 2.8V LDO (250mA), no RESET, SOT-223 package; lacks dual-output and integrated reset capability. | Only suitable for replacing OUT1 alone; requires external reset IC and second regulator for full MAX8530EBTB2-T functionality. | Choose only for redesigns where dual-rail integration is unnecessary and layout allows discrete reset implementation. |
Compared with MAX8530ETTK2-T, the MAX8530EBTB2-T offers superior space efficiency but lower thermal headroom; compared with TPS79528DCQ, it delivers complete dual-rail + reset integration in one die, reducing component count and improving system reliability.

FAQ
What output voltages does the MAX8530EBTB2-T provide?
The MAX8530EBTB2-T delivers fixed 2.8V on OUT1 and 1.8V on OUT2, as confirmed by its top-mark code "ACR" in the Output Voltage Selector Guide. These values are factory-trimmed and guaranteed over temperature and load, eliminating need for external feedback resistors.
Does the MAX8530EBTB2-T require external components to generate the RESET signal?
No - the MAX8530EBTB2-T integrates a dedicated reset circuit that monitors OUT1 voltage and asserts an open-drain active-low RESET signal when voltage drops below 87% of nominal. No external resistor divider, capacitor, or supervisory IC is required for basic reset functionality.
What is the maximum continuous output current supported by each regulator in the MAX8530EBTB2-T?
The MAX8530EBTB2-T guarantees 200mA on OUT1 and 150mA on OUT2 under all operating conditions. Electrical Characteristics table confirms minimum current-limit thresholds of 210mA (OUT1) and 165mA (OUT2), ensuring robust overload handling.
Can the MAX8530EBTB2-T operate from a single alkaline cell?
Yes - with a minimum input voltage of 2.5V, the MAX8530EBTB2-T supports operation from fresh single-cell alkaline (1.5V × 2 = 3.0V) or NiMH (1.2V × 2 = 2.4V, marginally below spec). For reliable two-cell NiMH use, consider input boost or verify actual loaded voltage remains ≥2.5V.
Is the UCSP package of the MAX8530EBTB2-T compatible with standard reflow processes?
Yes - the MAX8530EBTB2-T's 6-bump UCSP package is qualified for standard Pb-free reflow profiles per JEDEC J-STD-020. Its 0.6mm height and defined solder bump geometry enable reliable assembly using standard stencil printing and reflow ovens.
