BL8568 Power Management IC – 500mA CMOS LDO Linear Regulator | 2.0–6.0V, SC70-5 / SOT23-3 / SOT23-5 / DFN1×1

The BL8568 is a low-noise CMOS low-dropout (LDO) linear regulator designed for battery-powered and portable applications requiring clean, stable power with moderate current output.
It supports an input voltage range of 2.0V to 6.0V and provides adjustable output voltages from 1.0V to 4.5V in 0.1V steps with ±2% accuracy.

Featuring high PSRR of 70dB @1kHz, fast transient response, and low quiescent current of 35µA, the BL8568 is ideal for mobile phones, wireless peripherals, and other portable consumer electronics. Its small SMD packages allow for flexible PCB design in space-constrained applications.
