LP3881 0.8A Fast-Response Ultra Low Dropout Linear Regulators
The LP3881 is a high-current, fast-response linear regulator fabricated on a CMOS process to maintain output voltage regulation with minimum input-to-output voltage drop. It operates from two independent input voltages: Vbias for the gate drive and Vin for the load power, allowing operation from ultra-low input voltages.
