Product details
Overview
MAX8530ETTM1 from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset circuitry, designed for space-constrained battery-powered systems. It delivers 200mA from OUT1 and 150mA from OUT2, operates from 2.5V to 6.5V input, achieves 100mV typical dropout at 100mA, and consumes only 130µA quiescent current - enabling extended runtime in cellular handsets and portable instrumentation.
For engineers reviewing the MAX8530ETTM1 datasheet, MAX8530ETTM1 pinout, MAX8530ETTM1 application, or MAX8530ETTM1 equivalent, key selection criteria include guaranteed dual-output current capability, open-drain active-low RESET timing (≥100ms), UCSP/QFN package compatibility, and thermal/short-circuit protection - all validated for operation across –40°C to +85°C.
Technical Context
The MAX8530ETTM1 integrates two independent P-channel MOSFET LDOs with internal 1.25V bandgap reference and error amplifiers. Each regulator uses an internal resistor divider for fixed output voltage selection (1.5V–3.3V in 50mV steps), and features separate current limiting (210mA min for OUT1, 165mA min for OUT2) and thermal shutdown at +160°C with 10°C hysteresis.
Its RESET function monitors OUT1 voltage exclusively, asserting an open-drain active-low signal when OUT1 falls below 87% of nominal (±3% accuracy over temperature), with 100ms minimum timeout and 200ms typical release delay after recovery - eliminating external reset ICs in baseband power sequencing for mobile SoCs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 6.5V - supports single-cell Li-ion, Li-poly, and multi-cell alkaline/NiMH inputs without pre-regulation. |
| OUT1 Output Current | 200mA guaranteed - sufficient for powering core logic or RF transceivers in handheld devices. |
| OUT2 Output Current | 150mA guaranteed - suitable for I/O voltage rails or auxiliary analog circuitry. |
| Dropout Voltage | 100mV typical at 100mA load - enables >95% efficiency at light-to-moderate loads near end-of-battery life. |
| Quiescent Current | 130µA with both LDOs active - ensures minimal standby drain during system sleep modes. |
| RESET Threshold | 87% of OUT1 nominal voltage (min 84%, max 89%) - provides precise undervoltage detection for reliable processor boot sequencing. |
| Shutdown Current | <1µA - reduces system leakage to negligible levels during deep-sleep or storage states. |
Pinout & Package
The MAX8530ETTM1 is supplied in a 6-pin thin QFN package with exposed pad (3mm × 3mm × 0.8mm), optimized for thermal dissipation in compact PCB layouts. The GND pin serves as both electrical reference and thermal path; soldering the exposed pad to a large ground plane is required for rated power handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT2 | Regulator 2 output terminal | Delivers up to 150mA at user-selected fixed voltage (1.5V–3.3V); requires ≥1µF output capacitor for stability. |
| 2 - IN | Main input supply connection | Accepts 2.5V–6.5V input; requires 2.2µF low-ESR ceramic capacitor placed adjacent to pin for noise suppression. |
| 3 - OUT1 | Regulator 1 output terminal | Delivers up to 200mA at user-selected fixed voltage; supplies primary core voltage (e.g., VCORE) in portable processors. |
| 4 - GND | Ground reference and thermal sink | Must be connected to PCB ground plane via multiple vias under exposed pad to maintain junction temperature ≤+150°C. |
| 5 - SHDN | Logic-controlled enable/disable input | Active-high control: tie to IN for always-on operation; drive low to reduce total supply current to <1µA. |
| 6 - RESET | Open-drain active-low reset output | Monitors OUT1 only; asserts low when OUT1 drops below threshold; requires external pull-up for µP interface. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous generation of two distinct, stable supply rails (e.g., VCORE + VI/O) from single input source. |
| Integrated microprocessor RESET | Eliminates need for discrete reset supervisor IC and external RC timing network in portable baseband designs. |
| P-channel MOSFET pass devices | Delivers ultra-low quiescent current independent of load or dropout condition - critical for battery longevity. |
| Thermal and short-circuit protection | Prevents device failure during fault conditions; thermal shutdown cycles output during sustained overload without latch-up. |
| Ultra-small 3mm × 3mm QFN package | Reduces board area by >50% vs. comparable SOIC-8 regulators - essential for slim mobile form factors. |
Applications
| Cellular Handset Power Management | Digital Camera Core Supply |
|---|---|
Use Scenario: Regulating VCORE and VI/O rails for baseband processor and camera sensor interface in GSM/UMTS handsets. IC Role / Device Role / Timing Role: Dual-LDO provides tightly regulated, sequenced power domains; RESET ensures clean boot after battery insertion or brownout recovery.

IC Role / Device Role / Timing Role: OUT1 supplies 2.5V RF front-end; OUT2 supplies 1.5V digital baseband; RESET coordinates WLAN module initialization sequence. Use Value: 60dB PSRR at 100Hz suppresses switching noise from host CPU VRMs; 100ms RESET timeout satisfies IEEE 802.11 power-on timing specs. |
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 | Same die, identical electrical specs, but fixed 2.8V/1.8V output configuration (vs. ETTM1's unspecified output per ordering guide). | Pre-configured for common VCORE/VI/O pairing; no custom voltage option. | Select ETTK2 if 2.8V/1.8V outputs match design; ETTM1 requires verification of actual output voltages from top-mark code. |
| TLC7733QPWR | Single-output LDO (3.3V only) with reset; lacks second regulator, higher quiescent current (250µA), no thermal shutdown. | Suitable only for single-rail systems requiring basic reset supervision - not a functional replacement for dual-output use cases. | Use only where dual regulation is unnecessary; requires external LDO for second rail and additional thermal management. |
Compared with MAX8530ETTK2, the MAX8530ETTM1 offers identical protection and performance but requires confirmation of its specific output voltages via top-mark decoding; versus TLC7733QPWR, it delivers true dual-rail integration with lower IQ and comprehensive fault protection - making it superior for space- and power-sensitive portable designs.

FAQ
What output voltages does the MAX8530ETTM1 provide?
The MAX8530ETTM1 is a member of the MAX8530 family with configurable fixed outputs between 1.5V and 3.3V in 50mV increments. Its exact voltages depend on the top-mark code (e.g., "AER" = 2.8V/1.8V); the "M1" suffix indicates a specific factory configuration - consult the Output Voltage Selector Guide or top-mark decoding table to confirm nominal OUT1 and OUT2 values for this particular MAX8530ETTM1 unit.
Does the MAX8530ETTM1 include thermal protection?
Yes, the MAX8530ETTM1 incorporates thermal-overload protection that disables both LDO outputs when the junction temperature exceeds +160°C. After shutdown, the device automatically recovers once the die cools by 10°C, resulting in pulsed output during continuous overload - safeguarding the MAX8530ETTM1 and surrounding circuitry without requiring external intervention.
How does the RESET function operate in the MAX8530ETTM1?
The MAX8530ETTM1's RESET output is an open-drain, active-low signal that monitors only the OUT1 rail. It asserts low when OUT1 falls below 87% of its nominal voltage (with ±3% tolerance over temperature) and remains low for a minimum of 100ms. RESET releases high 200ms (typ) after OUT1 recovers to regulation - providing robust power-on reset timing for microprocessors without external components.
What package type is used for the MAX8530ETTM1?
The MAX8530ETTM1 is packaged in a 6-pin thin QFN with exposed thermal pad (3mm × 3mm × 0.8mm; pkg code T633-2). This RoHS-compliant package features pins numbered counterclockwise from the pin-1 indicator, with the exposed pad electrically connected to GND and requiring soldering to a PCB ground plane for optimal thermal performance and power dissipation.
Can the MAX8530ETTM1 be used with ceramic output capacitors?
Yes, the MAX8530ETTM1 is optimized for ceramic output capacitors. Use ≥2.2µF for OUT1 (or ≥1µF if load <150mA) and ≥1µF for OUT2, with X5R or X7R dielectrics recommended for stable capacitance across –40°C to +85°C. Avoid Z5U/Y5V types below –10°C unless capacitance is increased to ≥4.7µF - ensuring regulation stability under all operating conditions for the MAX8530ETTM1.
