General Description
The AS1353/AS1356 are high-performance, fixed-voltage linear LDOs designed for use with capacitors of 1 to 10µF. The devices can deliver superior performance even under low dropout conditions when the power transistor operates in linear mode.
The integrated P-channel MOSFET output allows the devices to maintain a low supply-current at loads of up to150mA. A shutdown mode includes logic-controlled circuitry which reduces shutdown current to less than 1µA (max).
