ISL9008
Low Noise LDO with Low I
Q
and High
PSRR
ISL9008 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 ISL9008 has a high PSRR of 65dB and output noise
less than 45µV
RMS
. When coupled with a no load quiescent
current of 45µA (typical), and 0.5µA shutdown current, the
ISL9008 is an ideal choice for portable wireless equipment.
The ISL9008 comes in several fixed voltage options with
±1.8% output voltage accuracy over temperature, line and
load. Other output voltage options are available on request.
