Dual Low-Dropout Linear
Regulators with RESET or Low-Noise Output in UCSP or QFN
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 prote...
