BL8079AG Power Management IC – 600mA High-PSRR Adjustable CMOS LDO Linear Regulator | DFN1.2×1.2-6L, SOT23-5

The BL8079AG is a high-performance CMOS LDO linear regulator designed for portable and battery-powered systems that demand high PSRR, fast transient response, and output discharge functionality.
It operates over a 1.5V to 6.0V input voltage range and provides an adjustable output voltage from 0.8V to 5.0V, using a precise 0.8V internal reference with ±2% output accuracy.

Featuring 65dB PSRR at 1kHz and a low quiescent current of 65µA, the BL8079AG ensures clean and efficient power delivery. With a higher output current capability of up to 600mA, it is suitable for more demanding loads while remaining compact in DFN1.2×1.2-6L and SOT23-5 packages.
