BL8071G Power Management IC – 1.5A High-PSRR CMOS LDO Linear Regulator | SOT223 / DFN3×3-6L

The BL8071G is a high-PSRR CMOS LDO linear regulator optimized for battery-powered systems, PC peripherals, and wireless devices that demand clean and stable power rails.
It supports an input voltage range of 1.5V to 6.0V and delivers adjustable output voltages from 1.1V to 5.0V in 0.1V steps, with ±2% / ±1% accuracy.

Compared to the standard BL8071, the BL8071G emphasizes higher ripple rejection (65dB @1kHz) while maintaining a low quiescent current of 100µA. It can supply up to 1.5A output current, making it suitable for higher-load applications.
