Description
The MAX8530/MAX8531 offer the benefits of low-dropout voltage and ultra-low power regulation in subminiaturized UCSP and QFN packages with an integrated 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-bar signal when OUT1 drops below 87% of the nominal output voltage. The MAX8531 includes a reference bypass pin for low output noise (40µVRMS).

Both devices include a logic-controlled shutdown input and are available in 6-bump UCSP and 6-pin thin QFN exposed pad packages.

Key Features   Applications/Uses
