ADP121-AUJZ33R7 Description

Short technical summary and product information.

The ADP121-AUJZ33R7 from Analog Devices is a low quiescent current, low dropout linear regulator designed for battery-powered applications. It operates from an input voltage range of 2.3 V to 5.5 V and can supply up to 150 mA of output current. The regulator features a low dropout voltage of 90 mV at a 150 mA load, improving efficiency.

 

Key electrical specifications include a low quiescent current of 11 µA with no load and 30 µA at full load, making it suitable for power-sensitive devices. It offers an output voltage range from 1.2 V to 3.3 V with an accuracy of ±1%. Protection features include current limit and thermal overload protection.

 

The ADP121-AUJZ33R7 is supplied in a 5-lead TSOT-23-5 package, which is a surface-mount type. This compact package is ideal for applications where space is limited, such as mobile phones and portable electronic devices. The regulator is designed for stable operation with small 1 µF ceramic output capacitors.
