150 mA NanoPower LDO Linear Regulator

Manufacturer's part number :


Manufacturer Skyworks


Description :

The AAT3220 PowerLinear NanoPower low dropout (LDO) linear regulator is ideal for portable applications where extended battery life is critical. This device features extremely low quiescent current, typically 1.1μA. Dropout voltage is also very low, typically less than 225mV at the maximum 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 shut down the LDO regulator during extended over-current events. The AAT3220 is available in a Pb-free, space-saving SC59 package. The device is rated over the -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 are similar products for this application, especially when a shutdown mode is required for further power savings.
