Analog Devices Inc./Maxim Integrated MAX8530EBTJJ+T

Overview

MAX8530EBTJJ+T from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset circuit, delivering 2.85V/200mA (OUT1) and 2.85V/150mA (OUT2) from 2.5V–6.5V input in a 6-bump UCSP package. It features 100mV typical dropout at 100mA, 130µA quiescent current, and open-drain active-low RESET output with 100ms minimum timeout-designed for baseband power management in battery-powered handheld devices.

For engineers reviewing the MAX8530EBTJJ+T datasheet, MAX8530EBTJJ+T pinout, MAX8530EBTJJ+T application, or MAX8530EBTJJ+T equivalent, key selection criteria include guaranteed dual-output current capability, reset threshold tracking OUT1 at 87% nominal voltage, ultra-low shutdown current (<1µA), thermal and short-circuit protection, and compatibility with ceramic output capacitors down to 1µF for OUT2.

Technical Context

The MAX8530EBTJJ+T integrates two independent P-channel MOSFET LDOs with internal 1.25V bandgap reference, error amplifiers, and feedback dividers. Its reset block monitors OUT1 voltage and asserts an open-drain active-low signal when falling below 87% of nominal output, with 100ms minimum timeout and 0.5% hysteresis.

Shutdown control is logic-driven via SHDN pin; pulling low disables both regulators and reduces supply current to <1µA. Thermal protection activates at +160°C junction temperature with 10°C hysteresis, enabling pulsed operation under sustained overload without damage.

Key Specifications

Pinout & Package

MAX8530EBTJJ+T is housed in a lead-free 6-bump UCSP package measuring 1.16mm × 1.57mm × 0.6mm with a 0.5mm pitch. The die attach pad is not electrically connected; thermal dissipation relies on solder joint conduction through bumps to PCB copper.

FAQ

What output voltages does the MAX8530EBTJJ+T provide?

The MAX8530EBTJJ+T delivers fixed 2.85V on both OUT1 and OUT2, as confirmed by its top-mark "ACG" in the Output Voltage Selector Guide. This dual 2.85V configuration supports baseband processor core and I/O rail requirements simultaneously without external feedback components.

Does the MAX8530EBTJJ+T include a reset function, and how is it triggered?

Yes, the MAX8530EBTJJ+T includes an open-drain, active-low RESET output that monitors OUT1 voltage. It asserts when OUT1 falls below 87% of its nominal 2.85V output (i.e., ~2.48V), with a minimum timeout of 100ms and 0.5% hysteresis-ensuring robust microprocessor reset during brownout conditions.

What is the maximum continuous output current for each regulator in the MAX8530EBTJJ+T?

The MAX8530EBTJJ+T guarantees 200mA for OUT1 and 150mA for OUT2 under all operating conditions. Electrical Characteristics table confirms minimum current limit thresholds of 210mA (OUT1) and 165mA (OUT2), providing design margin for transient peaks.

How does the MAX8530EBTJJ+T manage power efficiency in battery-powered systems?

The MAX8530EBTJJ+T achieves high battery efficiency via 130µA total quiescent current (both LDOs active), <1µA shutdown current, and P-channel MOSFET pass transistors that minimize dropout voltage proportionally to load. This extends usable battery life especially in standby and light-load states.

What package type and dimensions does the MAX8530EBTJJ+T use?

The MAX8530EBTJJ+T uses a lead-free 6-bump UCSP package measuring 1.16mm × 1.57mm × 0.6mm with 0.5mm bump pitch. Its ultra-compact footprint is optimized for space-constrained portable electronics, and the GND bumps serve as primary thermal conduction path to PCB copper.
