Description

General part information

ADP122 Series

The ADP122 /ADP123are low quiescent current, low dropout linear regulators. They are designed to operate from an input voltage between 2.3 V and 5.5 V and to provide up to 300 mA of output current. The low 85 mV dropout voltage at a 300 mA load improves efficiency and allows operation over a wide input voltage range.The low 170 μA of quiescent current at full load makes the ADP122 ideal for battery-operated portable equipment.The ADP122 is capable of 31 fixed output voltages from 1.75 V to 3.3 V. The ADP123 is the adjustable version of the device and allows the output voltage to be set between 0.8 V and 5.0 V by an external voltage divider.The ADP122 / ADP123 are specifically designed for stable operation with tiny 1 μF ceramic input and output capacitors to meet the requirements of high performance, space constrained applications.The ADP122 / ADP123 have an internal soft start that gives a constant start-up time of 350 μs. Short-circuit protection and thermal overload protection circuits prevent damage in adverse conditions. The ADP122 / ADP123 are available in a tiny, 5-lead TSOT package and 6-lead LFCSP package for the smallest footprint solution to meet a variety of portable applications.APPLICATIONSDigital camera and audio devicesPortable and battery-powered equipmentAutomatic meter reading (AMR) metersGPS and location management unitsMedical instrumentationPoint-of-sale equipment
