AAT3200
OmniPower™ LDO Linear Regulator
General Description
Features
PowerLinear™
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.
• 250mA Output for SOT-89 Package
• 150mA Output for SC59 Package
• 20µA Quiescent Current
• Low Dropout: 200mV (typical)
• High Accuracy: ±2.0%
• Current Limit Protection
• Over-Temperature Protection
• Low Temperature Coefficient
• Factory-Programmed Output Voltages:
1.8V to 3.5V
• Stable Operation With Virtually Any Output
Capacitor Type
• 3-Pin SOT-89 and SC59 Packages
Applications
The AAT3201 is a similar product for this applica-
tion, especially when a shutdown mode is required
for further power savings.
