The ADP122AUJZ-3.3-R7 is a CMOS Linear Regulator designed to operate from an input voltage between 2.3 and 5.5V and to provide up to 300mA of output current. The low 85mV dropout voltage at a 300mA load improves efficiency and allows operation over a wide input voltage range. The low 170µA of quiescent current at full load makes the ADP122 ideal for battery-operated portable equipment. It is capable of 31 fixed output voltages from 1.75 to 3.3V. The ADP122 is specifically designed for stable operation with tiny 1µF ceramic input and output capacitors to meet the requirements of high performance, space constrained applications. This regulator has an internal soft start that gives a constant start-up time of 350µs. Short-circuit protection and thermal overload protection circuits prevent damage in adverse conditions.
