1 / 16 page  General Description 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. 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. The AAT3221/2 is a similar product for this appli- cation, especially when a shutdown mode is required for further power savings.
