AAT3221/AAT3222: 150 mA Nanopower^TMLDO Linear

Regulator

Applications

Description

The AAT3221 and AAT3222 NanoPower™ Low Drop Out (LDO)

linear regulators are ideal for portable applications where

extended battery life is critical. These devices feature extremely

low quiescent current, typically 1.1 µA. Dropout voltage is also

very low, typically less than 200 mV at the maximum output

current of 150 mA. The AAT3221/3222 have an enable pin which,

when asserted, places the LDO regulator into shutdown mode,

removing power from its load and offering extended power

conservation capabilities for portable battery-powered

applications.

• Cellular phones

• Digital cameras

• Handheld electronics

• Notebook computers

• PDAs

• Portable communication devices

• Remote controls

The AAT3221/3222 have output short-circuit and over-current

protection. In addition, the devices also have an over-temperature

protection circuit that shuts down the LDO regulator during

extended over-current events. Both devices are available with

active high or active low enable input.

Features

• Quiescent current: 1.1 µA

• Low dropout: 200 mV (typical)

• Guaranteed output: 150 mA

• High accuracy: ±2%

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. Since only a small, 1 µF

ceramic output capacitor is recommended, often the only space

used is that occupied by the AAT3221 or AAT3222. The

AAT3221/3222 provide a compact and cost-effective voltage

conversion solution.

• Current limit protection

• Over-temperature protection

• Extremely low power shutdown mode

• Low temperature coefficient

• Factory-programmed output voltages: 1.5 V to 3.5 V

• Stable operation with virtually any output capacitor type

• Active high or low enable pin

Both devices are similar to the AAT3220, with the exception that

they offer further power savings with an enable pin.

A typical application circuit is shown in Figure 1. The pin

configuration is shown in Figures 2, 3, and 4. Signal pin

assignments and functional pin descriptions are provided in

Table 1.

• Small, 5-pin SOT23 or 8-pin SC70JW (AAT3221 only) package
