Product details
Overview
MAX8530ETT8J-T from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset functionality, designed for space-constrained battery-powered systems. It delivers 200mA on OUT1 and 150mA on OUT2, features 100mV typical dropout at 100mA load, 130µA quiescent current, and an open-drain active-low RESET output triggered when OUT1 falls below 87% of nominal voltage - used in cellular phones, PDAs, and digital cameras.
For engineers reviewing the MAX8530ETT8J-T datasheet, MAX8530ETT8J-T pinout, MAX8530ETT8J-T application, or MAX8530ETT8J-T equivalent, this page provides verified technical context, package mapping, pin-level circuit roles, real-world use scenarios, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The MAX8530ETT8J-T integrates two independent LDO regulators using internal P-channel MOSFET pass transistors, enabling ultra-low quiescent current (130µA) independent of load or dropout condition. Its reset block monitors OUT1 only and asserts a minimum 100ms active-low timeout after undervoltage detection.
It operates from 2.5V to 6.5V input, supports output voltages from 1.5V to 3.3V in 50mV increments, and includes thermal shutdown (160°C trip), short-circuit protection, and independent current limiting (210mA min for OUT1, 165mA min for OUT2).
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 battery inputs without external pre-regulation. |
| OUT1 Output Current | 200mA guaranteed - sufficient for baseband processor core (VCORE) or memory I/O rails in portable devices. |
| OUT2 Output Current | 150mA guaranteed - suitable for auxiliary logic, RF transceivers, or sensor subsystems. |
| Dropout Voltage | 100mV (typ) at 100mA - extends usable battery life by allowing regulation down to VIN = VOUT + 0.1V. |
| Quiescent Current | 130µA with both LDOs enabled - minimizes standby power loss in always-on subsystems. |
| RESET Threshold | 87% of OUT1 nominal voltage (min 84%, max 89%) - ensures reliable microprocessor reset before logic corruption occurs. |
| Shutdown Current | <1µA - enables deep-sleep modes in handheld instruments and wireless LAN cards. |
Pinout & Package
MAX8530ETT8J-T 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 to the board ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT2 | Regulator 2 output terminal | Delivers up to 150mA; requires ≥1µF ceramic output capacitor for stability. |
| 2 - IN | Main input supply connection | Accepts 2.5V–6.5V; requires 2.2µF input capacitor for line transient suppression. |
| 3 - OUT1 | Regulator 1 output terminal | Delivers up to 200mA; supplies primary core rail (e.g., VCORE); monitored by RESET block. |
| 4 - GND | Ground reference and thermal sink | Must be soldered to large copper area or ground plane to maintain junction temperature ≤+150°C. |
| 5 - SHDN | Logic-controlled shutdown input | Active-high; drives low to reduce total supply current to <1µA; internally pulled up when unconnected. |
| 6 - RESET | Open-drain, active-low reset output | Asserted when OUT1 drops below threshold; minimum 100ms timeout; requires external pull-up resistor. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous powering of core (OUT1) and I/O (OUT2) rails with separate accuracy and load handling. |
| Integrated microprocessor reset | Eliminates external reset IC and voltage divider components; reduces BOM count and layout area in portable designs. |
| P-channel MOSFET pass transistors | Delivers stable 130µA quiescent current across all load and dropout conditions - critical for battery runtime. |
| Thermal and short-circuit protection | Allows indefinite output shorting and automatic recovery from overload without latch-up or damage. |
| 6-pin thin QFN with exposed pad | 3mm × 3mm footprint fits high-density mobile PCBs; exposed pad improves thermal resistance by >50% vs. standard QFN. |
Applications
| Cellular Phones | Digital Cameras |
|---|---|
|
Use Scenario: Powering baseband processor core (VCORE) and memory interface in GSM/UMTS handsets. IC Role / Device Role / Timing Role: Dual-LDO regulator providing tightly regulated 2.85V (OUT1) and 1.8V (OUT2) rails; RESET monitors VCORE to prevent boot failure during brownout. Use Value: 100mV dropout extends usable battery range by ~150mV per cell; 130µA IQ preserves standby time over weeks. |
Use Scenario: Supplying image sensor analog front-end and ISP core in compact point-and-shoot cameras. IC Role / Device Role / Timing Role: OUT1 powers noise-sensitive analog sensor bias (2.8V), OUT2 powers digital ISP logic (1.8V); RESET ensures clean boot after cold start. Use Value: Independent current limits prevent sensor rail collapse during flash LED surge; thermal protection avoids shutdown during burst capture. |
| PDAs and Palmtop Computers | Wireless LAN Cards |
|
Use Scenario: Regulating CPU core and peripheral I/O rails in ARM-based handheld computing platforms. IC Role / Device Role / Timing Role: OUT1 (2.6V) supplies CPU core; OUT2 (1.8V) powers SDIO interface; RESET synchronizes with bootloader initialization sequence. Use Value: 200mA/150mA output capability meets peak transient demands of burst-mode operation without voltage droop. |
Use Scenario: Providing stable 3.0V and 1.8V rails for WLAN SoC and RF front-end in Mini-PCI and M.2 modules. IC Role / Device Role / Timing Role: OUT1 powers WLAN baseband (3.0V), OUT2 powers RF transceiver (1.8V); RESET prevents firmware hang during antenna switching transients. Use Value: 60dB PSRR at 100Hz suppresses switching noise from nearby DC-DC converters; 100ms RESET timeout accommodates slow power-rail ramp-up. |
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 |
|---|---|---|---|
| MAX8530EBTJJ-T | Same dual-LDO + RESET function but in 6-bump UCSP (1.16mm × 1.57mm); no exposed pad; higher thermal resistance. | Better suited for ultra-thin wearables where 3mm × 3mm QFN is too tall; less effective heat spreading under sustained 200mA load. | Select when board height <0.6mm is mandatory and average load <100mA; avoid for thermally constrained industrial handhelds. |
| TPS79533DBVR | Single 3.3V LDO (500mA), no RESET, no second output; 170µA IQ; SOT-23-5 package. | Requires external reset IC and second regulator for dual-rail systems - increases component count and layout area. | Only viable if redesign allows splitting rails and adding discrete reset; not a functional substitute for MAX8530ETT8J-T's integrated dual-output + RESET. |
Compared with MAX8530EBTJJ-T, MAX8530ETT8J-T offers superior thermal performance and higher current headroom in the same pin count; compared with TPS79533DBVR, it eliminates two external components and supports true dual-rail sequencing with built-in monitoring.

FAQ
What output voltage options are available for MAX8530ETT8J-T?
The MAX8530ETT8J-T supports factory-set output voltages between 1.5V and 3.3V in 50mV increments. Specific variants include 2.8V/1.8V (as indicated by "8J" in the part number), with other combinations like 2.85V/2.6V or 2.5V/1.8V available under different suffixes. Custom voltages require minimum order quantities.
Does MAX8530ETT8J-T require external components for basic operation?
Yes - MAX8530ETT8J-T requires a 2.2µF input capacitor, ≥2.2µF output capacitor on OUT1, ≥1µF on OUT2, and an external pull-up resistor on the RESET pin. No external feedback resistors are needed since output voltages are factory-trimmed and internally set.
How does the RESET function of MAX8530ETT8J-T behave during power-down?
During power-down, the MAX8530ETT8J-T asserts RESET low when OUT1 falls below 87% of its nominal voltage. The RESET signal remains low until OUT1 rises above threshold and sustains for ≥100ms, ensuring microprocessor reset persists through full rail collapse.
Can MAX8530ETT8J-T operate with a 1.2V input supply?
No - MAX8530ETT8J-T has a minimum input voltage of 2.5V and an undervoltage lockout threshold of 2.25V (typ). Operation below 2.5V is outside specification and will cause dropout or disable regulation; it cannot regulate 1.2V inputs.
Is MAX8530ETT8J-T pin-compatible with MAX8531 variants?
No - MAX8530ETT8J-T includes a RESET pin (Pin 6), while MAX8531 uses Pin 6 as BP (bypass) for low-noise operation. Their pinouts differ functionally; substituting one for the other without board revision will result in incorrect or nonfunctional behavior.
