BL8079G Power Management IC – 300mA High-PSRR Adjustable CMOS LDO Linear Regulator | SOT23-5

Shanghai Belling

The BL8079G is a high-PSRR CMOS LDO linear regulator optimized for battery-powered and portable applications requiring fast transient response and controlled output discharge.
It supports a 2.0V to 6.0V input voltage range and provides an adjustable output voltage from 0.8V to 5.0V using an internal 0.8V reference, ensuring flexible voltage configuration with ±2% accuracy.

With a PSRR of 65dB at 1kHz and a low quiescent current of just 65µA, the BL8079G minimizes power loss while maintaining clean output rails. It can deliver up to 300mA output current and is housed in a compact SOT23-5 package, making it ideal for space-constrained designs.
