Overview
The ADP121-AUJZ30R7 is a low dropout linear regulator produced by Analog Devices Inc. This component is designed to operate with a wide input voltage range of 2.3 V to 5.5 V and provides up to 150 mA of output current. It is particularly suited for battery-operated portable equipment due to its low quiescent current of 30 μA at full load. The ADP121-AUJZ30R7 is available in a compact 5-lead TSOT or 4-ball WLCSP package, making it ideal for applications where space is limited.
