Data Sheet
1 General Description
The AS1353/AS1356 are high-performance, fixed-volt-
age 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 tran-
sistor 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).
Integrated over-temperature and over-current protec-
tion circuitry switches the devices 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 dis-
connects 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 is limited
(380mA typ) via the on-chip current limiting circuitry.
Multiple output voltages are available as standard prod-
ucts: 3.6, 3.3, 3.0, 2.7, 2.5, or 1.5V. All devices are avail-
able in a 5-pin SOT23 package.
