AAT3232

$1$/2*,& 7(&+ General Description TM www.DataSheet4U.com AAT3232 300mA CMOS Low Drop Out Linear Regulator Features Low Dropout - 300mV (max) at 300mA Guaranteed 300mA Output High accuracy 30µA Quiescent Current Current limit protection Short circuit current fold back Over-Temperature protection Noise reduction bypass capacitor Shutdown mode for longer battery life Low Temperature coefficient 7 Factory programmed output voltages SOT-23 5-pin package The AAT3232 Low Dropout Linear Regulator is ideal for portable applications where longer battery life is critical. It features low quiescent current (30µA typical) and low dropout voltage (300mV max) at full output current. The device is able to protect itself from short circuit conditions with fold back current limiting. Thermal shutdown is activated to prevent damage under extreme conditions. The AAT3232 also features a low-power shutdown mode for longer battery life. A pin is provided to improve PSRR performance, by connecting an external capacitor from the AAT3232’s reference output to ground. The AAT3232 is available in a space saving 5-pin SOT-23 in 7 factory programmed voltages of 2.5V, 2.7V, 2.8V, 3.0V, 3.3V, 3.5V and 3.8V.
