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

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

ꢀ Thermal-Overload and Short-Circuit Protection

ꢀ Output Current Limit

ꢀ Tiny Packages Available

1.16 x 1.57 x 0.6mm UCSP (3 x 2 Grid)

3mm x 3mm Thin QFN

(40µV

RMS

Both devices include a logic-controlled shutdown input

and are available in 6-bump UCSP and 6-pin thin QFN

exposed pad packages.
