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 which is
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 SOT23
package or a 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.
