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.
