Low Noise LDO with Low I
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 20µV
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.
