PRODUCT DATASHEET

AAT3221/2

PowerLinear^TM

150mA NanoPower™ LDO Linear Regulator

General Description

Features

The AAT3221 and AAT3222 PowerLinear NanoPower low

dropout (LDO) linear regulators are ideal for portable

applications where extended battery life is critical.

These devices feature extremely low quiescent current,

typically 1.1μA. Dropout voltage is also very low, typi-

cally less than 200mV at the maximum output current of

150mA. The AAT3221/2 have an enable pin feature

which, when asserted, will enter the LDO regulator into

shutdown mode, removing power from its load and offer-

ing extended power conservation capabilities for portable

battery-powered applications.

• 1.1μA Quiescent Current

• Low Dropout: 200mV (typical)

• Guaranteed 150mA Output

• High Accuracy: ±2%

• Current Limit Protection

• Over-Temperature Protection

• Extremely Low Power Shutdown Mode

• Low Temperature Coefficient

• Factory-Programmed Output Voltages

▪ 1.5V to 3.5V

• Stable Operation With Virtually Any Output Capacitor

Type

• Active High or Low Enable Pin

• 4kV ESD

The AAT3221/2 have output short-circuit and over-cur-

rent protection. In addition, the devices also have an

over-temperature protection circuit, which will shut

down the LDO regulator during extended over-current

events. The devices are available with active high or

active low enable input.

• 5-Pin SOT23 or 8-Pin SC70JW Package

• -40°C to +85°C Temperature Range

Applications

• Cellular Phones

The AAT3221 and AAT3222 are available in Pb-free,

space-saving 5-pin SOT23 packages. The AAT3221 is

also available in a Pb-free, 8-pin SC70JW package. The

device is rated over the -40°C to +85°C temperature

range. Since only a small, 1μF ceramic output capacitor

is recommended, often the only space used is that occu-

pied by the AAT3221/2 itself. The AAT3221/2 provide a

compact and cost-effective voltage conversion solution.

• Digital Cameras

• Handheld Electronics

• Notebook Computers

• PDAs

• Portable Communication Devices

• Remote Controls

The AAT3221 and AAT3122 are similar to the AAT3220,

with the exception that they offer further power savings

with an enable pin.
