The PJ20050 is a 500 mA, ultra-high PSRR, ultra-low noise, high-accuracy, low-dropout CMOS linear regulator with high ripple rejection. Designed to meet the requirements of RF and analog circuits, this device consumes low quiescent current and provides fast line and load transient performance. The PJ20050 is a flexible device by supporting an input voltage range from 1.7 V to 6.0 V. This device has a fixed output voltage option of 0.65 V to 5.0 V and an externally adjustable output range of 0.55 V to 5.5 V, making the device flexible for post-regulation.
The PJ20050 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 a high-accuracy of ±1% (max) at 25°C. It is available in DFN2x2-6, and DFN1.2x1.2-6 packages.
