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 compensation is carried out internally unlike other LDOs where it is done externally. Since the output capacitor and noise bypass capacitor are able to be reduced, so saving the board design space.
When a CL capacitor is used, the IC can discharge the electric charge stored at the output capacitor through the internal switch while in standby state, and as a result the VOUT quickly returns to the VSS level. LR9203xL-xx-AE5-R
