ADP123AUJZ Part Information

Details for ADP123AUJZ by Analog Devices

Semiconductors - ICs>Power Management ICs - PMIC>Voltage Regulators

Part Description

The ADP122/ADP123 are 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.
