ISL9008A
FN6300.5
Low Noise LDO with Low IQ, High PSRR
ISL9008A 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 200mï.
The ISL9008A has a high PSRR of 65dB and output noise
less than 45µVRMS. When coupled with a no load quiescent
current of 46µA (typical), and 0.5µA shutdown current, the
ISL9008A is an ideal choice for portable wireless equipment.
The ISL9008A comes in several fixed voltage options with
±1.8% output voltage accuracy over-temperature, line and
load. Other output voltage options may be available upon
request.
