DATA SHEET AAT3220 TM 150mA NanoPower LDO Linear Regulator General Description Features The AAT3220 PowerLinear NanoPower low dropout (LDO) 1.1A Quiescent Current linear regulator is ideal for portable applications where Low Dropout: 200mV (typ) extended battery life is critical. This device features Guaranteed 150mA Output extremely low quiescent current, typically 1.1A. Dropout High Accuracy: 2.0% voltage is also very low, typically less than 225mV at the Current Limit and Over-Temperature Protection maximum output current of 150mA. The AAT3220 has Low Temperature Coefficient output short-circuit and over-current protection. In addi- Factory-Programmed Output Voltages: 1.8V to 3.5V tion, the device also has an over-temperature protection Stable Operation With Virtually Any Output Capacitor circuit which will shut down the LDO regulator during Type extended over-current events. 3-Pin SC59 Package 4kV ESD Rating The AAT3220 is available in a Pb-free, space-saving SC59 package. The device is rated over the -40C to +85C temperature range. Since only a small, 1F Applications ceramic output capacitor is required, often the only Cellular Phones space used is that occupied by the AAT3220 itself. The Digital Cameras AAT3220 is truly a compact and cost-effective voltage Handheld El ectronics conversion solution. Notebook Computers The AAT3221/2 are similar products for this application, PDAs especially when a shutdown mode is required for further Portable Communication Devices power savings.
