Product details
Overview
MAX8530ETTP2+ from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset functionality, delivering 2.5V/1.8V fixed outputs (OUT1/OUT2), 200mA/150mA guaranteed output current, and 100mV typical dropout at 100mA load. It operates from 2.5V to 6.5V input and features an open-drain active-low RESET output timed to OUT1 for power-on sequencing in portable baseband power supplies.
For engineers reviewing the MAX8530ETTP2+ datasheet, MAX8530ETTP2+ pinout, MAX8530ETTP2+ application, or MAX8530ETTP2+ equivalent, key selection criteria include dual-output voltage tracking, ultra-low 130µA quiescent current, thermal/short-circuit protection, and lead-free 3mm × 3mm thin QFN-EP package compatibility with space-constrained battery-powered designs.
Technical Context
The MAX8530ETTP2+ integrates two independent LDO regulators with P-channel MOSFET pass transistors, enabling low dropout proportional to load current and eliminating base-drive losses. Its internal 1.25V bandgap reference feeds error amplifiers that regulate OUT1 and OUT2 via internal resistor dividers - no external feedback required for fixed-voltage variants like this part.
RESET assertion is triggered when OUT1 falls below 87% of nominal (2.5V), holding low for ≥100ms; deassertion occurs after OUT1 rises above threshold and stabilizes. The SHDN pin provides logic-controlled shutdown, reducing supply current to <1µA while maintaining reset state integrity during sleep modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | OUT1 = 2.5V, OUT2 = 1.8V - factory-trimmed fixed outputs; no external resistors needed. |
| Max Output Current | 200mA on OUT1, 150mA on OUT2 - guaranteed across -40°C to +85°C ambient. |
| Dropout Voltage | 100mV (typ) at 100mA load - enables operation down to VIN = VOUT + 0.1V, extending battery life. |
| Quiescent Current | 130µA (both LDOs active) - constant vs. load/dropout, critical for standby power budgeting. |
| RESET Threshold | 87% of OUT1 nominal (2.175V) with 0.5% hysteresis - ensures reliable power-on reset timing without external components. |
| Shutdown Current | <1µA - supports deep-sleep states in handheld devices with minimal leakage impact. |
| Thermal Protection | 160°C shutdown with 10°C hysteresis - prevents damage during sustained overload or poor PCB thermal design. |
Pinout & Package
MAX8530ETTP2+ uses a 6-pin thin QFN package with exposed pad (3mm × 3mm × 0.8mm), optimized for thermal dissipation in compact layouts. The GND pin and exposed pad must be soldered to a large PCB ground plane to maintain junction temperature within safe limits under full load.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT2 | Regulator 2 output | Delivers fixed 1.8V at up to 150mA; requires ≥1µF output capacitor for stability. |
| 2 - IN | Main input supply | Accepts 2.5V–6.5V; requires 2.2µF low-ESR ceramic input capacitor near pin. |
| 3 - OUT1 | Regulator 1 output | Delivers fixed 2.5V at up to 200mA; requires ≥2.2µF output capacitor for full-load stability. |
| 4 - GND | Ground reference & thermal path | Electrical return and primary heat sink; must connect to large copper area or ground plane. |
| 5 - SHDN | Logic-controlled enable | Active-high; tie to IN for always-on operation; drives low to reduce IQ to <1µA. |
| 6 - RESET | Open-drain active-low reset | Monitors OUT1 only; asserts low when OUT1 drops below 2.175V; min 100ms timeout. |
Key Features
| Feature | Design Value |
|---|---|
| Dual fixed-output LDOs | 2.5V/1.8V outputs eliminate external feedback networks and simplify BOM for baseband/core rail separation. |
| Integrated reset circuit | Eliminates discrete supervisor IC and RC timing network - reduces component count and board area by ≥3 parts. |
| P-channel MOSFET pass devices | Enable ultra-low quiescent current independent of load or dropout, maximizing battery runtime in light-load states. |
| Thermal & short-circuit protection | Allows indefinite output shorting and automatic recovery from overheating - removes need for external fusing or monitoring. |
| Lead-free 3mm × 3mm QFN-EP | Meets RoHS requirements while providing superior thermal performance vs. UCSP; compatible with standard reflow profiles. |

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+ | Fixed 2.8V/1.8V outputs instead of 2.5V/1.8V; identical pinout, package, and RESET behavior. | Suitable for systems requiring higher baseband voltage; not drop-in for 2.5V-dependent analog circuits. | Select when VOUT1 = 2.8V aligns with system rail requirements; verify analog section tolerance to 2.8V. |
| MAX8530EBTJ2+ | Same 2.85V/1.8V outputs but in 6-bump UCSP (1.16mm × 1.57mm); 100mV dropout and 130µA IQ retained. | Better suited for ultra-space-constrained designs where QFN footprint is prohibitive. | Choose for smallest possible footprint; accept reduced thermal margin vs. QFN-EP due to smaller copper area. |
Compared with MAX8530ETTP2+, MAX8530ETTK2+ shifts OUT1 to 2.8V - useful for higher-voltage baseband but incompatible with 2.5V-referenced ADCs; MAX8530EBTJ2+ offers identical regulation in UCSP, trading thermal performance for extreme miniaturization.

FAQ
What output voltages does the MAX8530ETTP2+ provide?
The MAX8530ETTP2+ delivers fixed 2.5V on OUT1 and 1.8V on OUT2, factory-trimmed and verified across temperature. These values are encoded in the top-mark "AET" per the Output Voltage Selector Guide. No external resistors are needed, and the outputs remain stable under loads up to 200mA (OUT1) and 150mA (OUT2) with ≤3% accuracy over -40°C to +85°C.
Does the MAX8530ETTP2+ require external components for reset functionality?
No - the MAX8530ETTP2+ integrates a dedicated reset circuit that monitors only OUT1. It asserts an open-drain active-low RESET signal when OUT1 drops below 87% of 2.5V (2.175V), holding it low for ≥100ms. This eliminates external reset ICs, RC networks, or voltage dividers, reducing BOM count and layout complexity.
What package type and thermal considerations apply to the MAX8530ETTP2+?
The MAX8530ETTP2+ uses a 6-pin thin QFN with exposed pad (3mm × 3mm × 0.8mm). The GND pin and exposed pad must be soldered to a large PCB ground plane to dissipate heat - thermal resistance drops significantly with ≥200mm² copper area. Without proper grounding, junction temperature may exceed 150°C under full load, triggering thermal shutdown.
How does the MAX8530ETTP2+ behave during shutdown?
When SHDN is driven low, the MAX8530ETTP2+ disables both LDOs and pulls RESET low, drawing <1µA total supply current. OUT1 and OUT2 discharge through their loads; RESET remains asserted until SHDN returns high and OUT1 stabilizes above 2.175V. This behavior ensures deterministic power-down sequencing in battery-powered systems.
Is the MAX8530ETTP2+ pin-compatible with other MAX8530 variants?
Yes - all MAX8530 variants in the 6-pin thin QFN package (e.g., MAX8530ETTK2+, MAX8530ETTG2+) share identical pinout, footprint, and electrical interface. Voltage differences are internal only; swapping parts requires only firmware or schematic updates to match new output levels - no PCB revision needed.
