Product details
Overview
MAX8530ETT8J 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, 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, digital cameras, and PCMCIA cards.
For engineers reviewing the MAX8530ETT8J datasheet, MAX8530ETT8J pinout, MAX8530ETT8J application, or MAX8530ETT8J equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for dual-LDO power management in portable electronics.
Technical Context
The MAX8530ETT8J integrates two independent LDO regulators with P-channel MOSFET pass transistors, enabling ultra-low quiescent current (130µA) independent of load or dropout condition. Its internal 1.25V bandgap reference and error amplifiers regulate both outputs using internal feedback dividers, supporting fixed output voltages between 1.5V and 3.3V in 50mV steps.
The device includes a dedicated reset block monitoring OUT1 only, asserting an open-drain active-low RESET signal with ≥100ms timeout after undervoltage detection. Shutdown control via SHDN pin reduces supply current to <1µA, while thermal shutdown (160°C) and short-circuit protection ensure robust operation in handheld devices.
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 inputs without external pre-regulation. |
| OUT1 Output Current | Guaranteed 200mA - sufficient for baseband processor core (VCORE) or I/O rail in mobile SoC applications. |
| OUT2 Output Current | Guaranteed 150mA - suitable for auxiliary rails like camera sensor bias or RF front-end supplies. |
| Dropout Voltage | 100mV (typ) at 100mA - enables extended battery runtime by maintaining regulation down to VIN = VOUT + 0.1V. |
| Quiescent Current | 130µA (both LDOs on) - minimizes standby power loss in always-on subsystems such as real-time clocks or wake-up logic. |
| RESET Threshold | 87% of OUT1 nominal voltage (min 84%, max 89%) - ensures reliable microprocessor reset before functional failure during brownout. |
| Operating Temperature | -40°C to +85°C - qualified for industrial-grade portable equipment including handheld instruments and wireless LAN cards. |
Pinout & Package
MAX8530ETT8J is packaged in a 6-pin thin QFN with exposed pad (3mm × 3mm × 0.8mm), optimized for thermal dissipation in compact PCB layouts. The GND pin serves dual function: electrical ground reference and primary heat path to the PCB 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 under full load. |
| 2 - IN | Main input supply connection | Accepts 2.5V–6.5V; must be decoupled with ≥2.2µF low-ESR ceramic capacitor near the pin. |
| 3 - OUT1 | Regulator 1 output terminal | Delivers up to 200mA; supports VCORE or baseband processor rail; requires ≥2.2µF output capacitance. |
| 4 - GND | Ground reference and thermal sink | Must be soldered to large copper area or internal 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 | Monitors OUT1 only; asserts low when OUT1 drops below threshold; minimum 100ms timeout ensures clean µP reset. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous powering of core (OUT1) and I/O (OUT2) rails with separate accuracy and transient response. |
| Integrated microprocessor reset | Eliminates external reset IC and resistor divider; reduces BOM count and layout area in space-sensitive designs. |
| P-channel MOSFET pass transistor | Ensures quiescent current remains constant across load and dropout conditions - critical for battery life optimization. |
| Thermal and short-circuit protection | Auto-recovers after cooling by 10°C; allows indefinite short-circuit survival without latch-off or manual reset. |
| Ultra-small QFN package | 3mm × 3mm footprint with exposed pad - fits within tight spacing constraints of cellular phone mainboards and camera modules. |
Applications
| Cellular Phone Baseband Power | Digital Camera Sensor Bias |

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 | Same functionality and specs, but in 6-bump UCSP (1.16mm × 1.57mm) - 60% smaller footprint than QFN. | Preferred for ultra-compact designs where board area is more constrained than thermal budget (e.g., hearing aids). | Select MAX8530EBTJJ only if assembly process supports UCSP reflow and thermal limits allow lower power dissipation (308mW vs. 1951mW). |
| MAX8531ETT8A | Replaces RESET with BP (bypass) pin for 40µVRMS low-noise output; identical pinout and package but no reset function. | Suitable for noise-sensitive analog rails (e.g., RF synthesizer VCO supply) where reset monitoring is handled externally. | Choose MAX8531ETT8A only when low output noise is prioritized over integrated reset - not a drop-in replacement for MAX8530ETT8J. |
Compared with MAX8530EBTJJ, MAX8530ETT8J offers higher thermal performance and easier handling in SMT lines; compared with MAX8531ETT8A, it trades low-noise capability for system-level reliability via integrated reset - making it optimal for cost-sensitive, space-constrained portable devices requiring guaranteed power-on sequencing.

FAQ
What output voltage options are available for MAX8530ETT8J?
The MAX8530ETT8J is a factory-configured variant with fixed output voltages - based on Maxim's Output Voltage Selector Guide, the "8J" suffix corresponds to OUT1 = 2.8V and OUT2 = 1.8V. These values are laser-trimmed during production and not user-adjustable. Other combinations (e.g., 2.85V/2.6V or 2.5V/1.8V) are available under different part numbers like MAX8530ETTKO or MAX8530ETTP2, but MAX8530ETT8J itself is strictly 2.8V/1.8V.
Does MAX8530ETT8J support adjustable output voltages?
No, MAX8530ETT8J does not support adjustable output voltages. It is a fixed-output device with internal resistor dividers set at manufacture - OUT1 is trimmed to 2.8V ±3% and OUT2 to 1.8V ±3% across -40°C to +85°C. External feedback resistors cannot be added, as the FB pins are not exposed; all variants in the MAX8530 family use factory-programmed outputs between 1.5V and 3.3V in 50mV increments.
How does the RESET function of MAX8530ETT8J interact with the SHDN pin?
When SHDN is driven low, both LDO outputs disable and RESET goes low (active state) - this ensures the microprocessor remains held in reset during shutdown. Upon SHDN return to high, OUT1 ramps up first; RESET remains low until OUT1 reaches ≥87% of its nominal voltage, then stays asserted for ≥100ms before going high. This sequence guarantees safe power-on reset timing independent of input ramp rate.
Can MAX8530ETT8J operate with ceramic output capacitors smaller than 2.2µF?
Yes - for OUT1, a minimum 1µF ceramic capacitor is acceptable when load current is below 150mA; for OUT2, 1µF is sufficient at all rated loads. However, using <2.2µF may degrade load-transient response and PSRR above 10kHz. The datasheet specifies 2.2µF as the recommended value for full-spec operation across temperature and load, especially in battery-powered systems where ESR stability matters.
Is MAX8530ETT8J pin-compatible with MAX8531 variants?
MAX8530ETT8J and MAX8531 QFN variants share identical pinout and package dimensions, but they are not functionally interchangeable: MAX8530ETT8J has RESET on pin 6, while MAX8531 has BP (bypass) on pin 6. Swapping them without redesigning the PCB will leave the RESET signal unconnected or short the BP node, compromising either system supervision or output noise performance - neither is a drop-in replacement.
