BL8067A Power Management IC – 500mA CMOS LDO Linear Regulator | 1.5–6.0V, SOT23-5 / DFN1×1

The BL8067A is a high-current CMOS low-dropout (LDO) linear regulator designed for portable and battery-powered applications that require higher load capability with clean and stable output voltage.
It supports an input voltage range of 1.5V to 6.0V and provides fixed output voltages from 1.0V to 4.5V in 0.1V steps, maintaining ±2% output accuracy.

Featuring low noise, high PSRR up to 68dB @ 1kHz, and a fast transient response, the BL8067A also integrates an output discharge function for rapid output shutdown.
With a low quiescent current of 50µA and up to 500mA output current, it is ideal for compact designs requiring higher power delivery.
