General Description

The MAX8530/MAX8531 offer the benefits of lowdropout 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.
