with RESET or Low-Noise Output in UCSP or QFN
General Description
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.
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
(40μV RMS ).
Features
? 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 RMS Output Noise (MAX8531)
? Low 130μA Operating Supply Current
? <1μA Shutdown Current
? 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
Ordering Information
Both devices include a logic-controlled shutdown input
and are available in 6-bump UCSP and 6-pin thin QFN
