Dual Low-Dropout Linear Regulators

with RESET or Low-Noise Output in UCSP or QFN

General Description

Features

The MAX8530/MAX8531 offer the benefits of low-

dropout voltage and ultra-low power regulation in

subminiaturized UCSP and QFN packages with an inte-

grated microprocessor reset circuit (MAX8530 only).

The devices operate from a 2.5V to 6.5V input and

deliver up to 200mA and 150mA outputs with low

dropout of 100mV (typ) at 100mA. Designed with an

internal P-channel MOSFET pass transistor, the supply

current is kept at a low 130µA (with both LDOs on),

independent of the load current and dropout voltage.

Other features include short-circuit protection and

thermal-shutdown protection.

♦ Guaranteed 200mA Output Current for OUT1

♦ Guaranteed 150mA Output Current for OUT2

♦ Low 100mV (typ) Dropout at 100mA Load for

both LDOs

♦ Open-Drain, Active-Low 100ms (min) Reset Timer

(MAX8530)

♦ Low 40µV

Output Noise (MAX8531)

RMS

♦ Low 130µA Operating Supply Current

♦ <1µA Shutdown Current

♦ Thermal-Overload and Short-Circuit Protection

♦ Output Current Limit

The MAX8530 provides microprocessor open-drain,

active-low reset output to monitor OUT1, eliminating

external components and adjustments. The MAX8530

asserts a 100ms (min) RESET signal when OUT1 drops

below 87% of the nominal output voltage. The MAX8531

includes a reference bypass pin for low output noise
