BL8074G Power Management IC – 800mA High-PSRR CMOS LDO Linear Regulator | SOT89-3

The BL8074G is a high-PSRR CMOS LDO linear regulator designed for stable and low-noise power delivery in battery-powered and peripheral applications.
It operates over a 1.5V to 6.0V input voltage range and provides an adjustable output voltage from 1.2V to 5.0V in 0.1V steps, ensuring flexible voltage regulation with ±2% / ±1% accuracy.

With a PSRR of 65dB at 1kHz and a low quiescent current of 100µA, the BL8074G is well-suited for noise-sensitive and energy-efficient designs while delivering up to 800mA output current. The SOT89-3 package offers good thermal performance for higher load conditions.
