ISL9003A
Low Noise LDO with Low I
Q
, 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 1
μ
F of
MLCC output capacitance with an ESR of up to 200m
Ω
.
The ISL9003A has a very high PSRR of 90dB and output
noise is 20
μ
V
RMS
(typical). When coupled with a no load
quiescent current of 31
μ
A (typical), and 0.5
μ
A 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.
