The AS1353/AS1356 are high-performance, fixed-voltage linear LDOs designed for use with capacitors of 1 to 10F. 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 AS1356 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 1A (max).
Integrated over-temperature and over-current protection circuitry switches AS1356 off in case of thermal overload or output short-circuit conditions.
The AS1353/AS1356 are optimized for low equivalent series resistance (ESR) output capacitors. Additionally, all devices contain reversed battery protection which disconnects the internal circuitry and parasitic diodes if the battery is connected incorrectly.
The AS1356 also features power-OK circuitry which can be used to monitor output regulation.
All devices also feature an integrated error amplifier and built-in 1.25V reference, and output current of AS1356 is limited (380mA typ) via the on-chip current limiting circuitry.
Multiple output voltages of AS1356 are available as standard products: 3.6, 3.3, 3.0, 2.7, 2.5, or 1.5V. All devices are available in a 5-pin SOT23 package.
