AAT3220

150mA NanoPower™ LDO Linear Regulator

™

PowerLinear

General Description

Features

The AAT3220 PowerLinear™ NanoPower Low

Dropout Linear Regulator is ideal for portable appli-

cations where extended battery life is critical. This

device features extremely low quiescent current

which is typically 1.1µA. Dropout voltage is also

very low, typically less than 225mV at the maxi-

mum output current of 150mA. The AAT3220 has

output short circuit and over current protection. In

addition, the device also has an over temperature

protection circuit, which will shutdown the LDO reg-

ulator during extended over current events.

1.1 µA Quiescent Current

Low Dropout: 200 mV (typ)

Guaranteed 150mA Output

High accuracy: 2.0ꢀ

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 SOT-23 packages

4kV ESD Rating

The AAT3220 is available in a space saving SOT-23

package or a SOT-89 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,

often the only space used is that occupied by the

AAT3220 itself. The AAT3220 is truly a compact and

cost effective voltage conversion solution.

Applications

•

Cellular Phones

Notebook Computers

Portable Communication Devices

Handheld Electronics

Remote Controls

Digital Cameras

PDAs

The AAT3221/2 is a similar product for this appli-

cation, especially when a shutdown mode is

required for further power savings.
