ISL9003
Low Noise LDO with Low I
Q
And High
PSRR
ISL9003 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 ISL9003 has a very high PSRR of 90dB and output
noise is 20µV
RMS
(typical). When coupled with a no load
quiescent current of 30µA (typical), and 0.5µA shutdown
current, the ISL9003 is an ideal choice for portable wireless
equipment.
The ISL9003 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.
