ISL9003A
FN6299.1
Low Noise LDO with Low IQ, High PSRR
ISL9003A is a high performance single low noise, high
PSRR LDO that delivers a continuous 150mA of load
current. It has a low standby current and is stable with 1μF of
MLCC output capacitance with an ESR of up to 200mΩ.
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.
