AAT3200

OmniPower™ LDO Linear Regulator

General Description

The AAT3200 PowerLinear OmniPower low

dropout (LDO) linear regulator is ideal for systems

where a low-cost solution is required. This device

features extremely low quiescent current, typically

20µA. Dropout voltage is also very low, typically

200mV. The AAT3200 has output short-circuit and

over-current protection. In addition, the device has

an over-temperature protection circuit which will

shut down the LDO regulator during extended

over-current events.

The AAT3200 is available in a space-saving, Pb-

free SC59 or SOT-89 package (for applications

requiring increased power dissipation). The device

is rated over a -40°C to +85°C temperature range.

Since only a small, 1µF ceramic output capacitor is

required, the AAT3200 is a truly cost-effective volt-

age conversion solution.

The AAT3201 is a similar product for this applica-

tion, especially when a shutdown mode is required

for further power savings.
