BL8563 Power Management IC – 300mA CMOS LDO Linear Regulator | 2.0–6.0V, SC70-5 / SOT23 / DFN1×1

The BL8563 is a low-noise CMOS low-dropout (LDO) linear regulator suitable for battery-powered and portable devices that require stable and clean voltage outputs.
It operates over a 2.0V to 6.0V input range and provides adjustable output voltages from 1.0V to 4.5V in 0.1V steps with ±2% accuracy.

This regulator offers high PSRR up to 70dB @ 1kHz, fast response to load changes, and a low quiescent current of 35µA, making it ideal for mobile devices, reference voltage sources, and low-power circuits.
Multiple compact packages enable flexible PCB designs for space-constrained applications.
