ADP120 is a CMOS linear regulator with a 100mA output current, low quiescent current, and low dropout voltage. It is suitable for applications such as mobile phones, digital cameras, and portable devices.
The ADP120 is a low‑quiescent, low‑dropout linear regulator that operates from 2.3 V to 5.5 V and delivers up to 100 mA of output current. It offers a very low quiescent current (11 pA) and shutdown current (<1 pA), making it ideal for battery‑powered portable equipment. The device is available in 16 fixed output voltage options and in two compact packages: a 5‑lead TSOT and a 4‑ball 0.4 mm pitch WLCSP.
The datasheet provides detailed electrical specifications, typical performance curves, pin descriptions, thermal data, recommended capacitor selections, and an ordering guide. It also includes application circuits for mobile phones, digital cameras, and other portable devices, as well as guidance on PCB layout and ESD protection.
