BL8063 Power Management IC – 300mA CMOS LDO Linear Regulator | 2.0–6.0V, SC70-5 / SOT23 / DFN1×1

The BL8063 is a high-performance CMOS low-dropout (LDO) linear regulator designed for noise-sensitive and battery-powered applications.
It supports an input voltage range of 2.0V to 6.0V and offers fixed output voltages from 1.0V to 4.5V in 0.1V steps with ±2% accuracy.

Featuring low noise, high PSRR up to 70dB @ 1kHz, and a fast transient response, the BL8063 ensures stable and clean power delivery.
Its low quiescent current of 35µA and 300mA output capability make it ideal for portable electronics.
Multiple compact packages allow flexible PCB layout in space-constrained designs.
