The PJ20950A series is a 450 mA, ultra-high PSRR, ultra-low noise, high-accuracy, and low dropout CMOS linear regulator with high ripple rejection. The device is ideal for radio frequency and analog circuits for its low quiescent current consumption and fast line and load transient performance. The PJ20950A 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 PJ20950A 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 provide high accuracy of ±1% (max) at 25°C. The device is available in SOT23-5, DFN1x1-4 and WLCSP-4 (0.65 mm x 0.65 mm x 0.33 mm, pitch 0.35 mm) packages.
