LR9203 Overview
The UTC LR9203 is a CMOS-based low dropout regulator with high output voltage accuracy, low dropout, high PSRR and low quiescent current. The devices can provide stable output voltages even without a load capacitor CL. The CL capacitor-less is possible because phase pensation is carried out internally unlike other LDOs where it is done externally.
