ADP121-AUJZ18R7 Description

Short technical summary and product information.

The ADP121-AUJZ18R7 from Analog Devices is a CMOS linear regulator designed for low quiescent current and low dropout voltage applications. It operates within an input voltage range of 2.3 V to 5.5 V and can deliver an output current of up to 150 mA.

 

Key electrical specifications include a low quiescent current of 11 μA with no load and 30 μA at full load, making it suitable for battery-powered devices. The dropout voltage is a low 90 mV at a 150 mA load, enhancing efficiency. It also features high PSRR of 70 dB at 1 kHz and low output noise of 40 μV rms.

 

The regulator offers an output voltage accuracy of ±1% and is stable with a small 1 μF ceramic output capacitor. It includes current limit and thermal overload protection for reliability. The ADP121 series is available in a 5-lead TSOT package and a 4-ball 0.4 mm pitch WLCSP package, providing compact solutions for portable applications.

 

This linear regulator is well-suited for applications such as mobile phones, digital cameras, audio devices, and other portable or battery-powered equipment requiring post DC-to-DC regulation.
