Description

General part information

ADP124 Series

The ADP124 /ADP125are 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 500 mA of output current. The low 130 mV dropout voltage at a 500 mA load improves efficiency and allows operation over a wide input voltage range.The low 210 μA of quiescent current with a 500 mA load makes the ADP124 / ADP125 ideal for battery-operated portable equipment. The ADP124 is capable of 31 fixed-output voltages from 1.75 V to 3.3 V. The ADP125 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 ADP124/ADP125 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 ADP124 / ADP125 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 ADP124 / ADP125 are available in an 8-lead exposed paddle MSOP package. When compared with the standard MSOP package, the exposed paddle MSOP package has lower thermal resistance (θJA). The lower thermal resistance package allows the ADP124 / ADP125 to meet the needs of a variety of portable applications while minimizing the rise in junction temperature.APPLICATIONSDigital camera and audio devicesPortable and battery-powered equipmentAutomatic meter reading (AMR) metersGPS and location management unitsMedical instrumentationPoint of load power
