DATASHEET
ISL9021A
250mA Single LDO with Low I
Q
, Low Noise and High PSRR LDO
The ISL9021A is a single LDO, which provides high
performance, low input voltage and high PSRR. It delivers
guaranteed continuous 250mA load current and is stable with
1µF to 4.7µF of output capacitance (±30%) with an ESR range
of 5m to 400m.
The input voltage range for the ISL9021A is between 1.5V to
5.5V and the output voltage comes in many fixed voltage
options with ±1.8% accuracy over-temperature, line and load
ranges. The ISL9021A has typical PSRR of 75dB @ 10kHz and
50dB @ 1MHz.
The reverse current protection feature prevents current from
flowing back to the power source when the output voltage is
pulled higher than the input.
The ISL9021A is offered in tiny 4-bump 0.975mmx1.155mm
WLCSP and 1.6mmx1.6mm 6 Ld µTDFN packages.
