Low drop-out (LDO) voltage regulator
Intersil
The ISL9003A has a very high PSRR of 90dB and output noise is 20μVRMS (typical). When coupled with a no load quiescent current of 31μA (typical), and 0.5μA shutdown current, the ISL9003A is an ideal choice for portable wireless equipment.
The ISL9003A comes in many fixed voltage options with ±1.8% output voltage accuracy over temperature, line and load. Other output voltage options are available on request.
