BL8061 Power Management IC – 250mA Ultra-Low Power CMOS LDO | SOT23-3, SOT23-5, SOT89-3

The BL8061 is an ultra-low quiescent current CMOS LDO linear regulator designed for battery-powered and always-on applications that require minimal standby power consumption.
It supports a maximum input voltage of 16V and provides an adjustable output voltage from 1.1V to 5.0V with 0.1V step resolution.

With a typical quiescent current of only 2µA, the BL8061 significantly reduces power loss during idle operation while delivering up to 250mA output current.
Its wide input range and stable regulation make it well-suited for portable and low-power embedded designs.
