The DIO7960 series is a 250 mA, ultra-high PSRR, ultra-low noise, high-accuracy, low dropout CMOS linear regulator. The DIO7960 is designed for radio frequency and analog circuits. The device consumes low quiescent current and provides fast line and load transient performance. The DIO7960 operates over an input voltage range of 1.65 V to 5.5 V and supports fixed output voltage from 1 V to 3.3 V. The DIO7960 is designed to work with a 1 µF input and a 1 µF output ceramic capacitor, allowing for a small overall solution size. A precision band-gap and error amplifier provides a high accuracy of ±1% (max) at 25°C. It is available in WLCSP-4 (0.65 mm*0.65 mm*0.33 mm, pitch 0.35 mm) and DFN1*1-4 packages.
