ISL9021
FN6867.1
250mA Single LDO with Low IQ, Low
Noise and High PSRR LDO
The ISL9021 is a single LDO providing high performance
low input voltage, 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
5mΩ to 400mΩ.
The input voltage range for the ISL9021 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. Other output voltage within the range of 0.9V to 3.3V
may be available upon request. The ISL9021 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 ISL9021 is offered in tiny 4-bump 1.155mmx0.975mm
WLCSP and 1.6mmx1.6mm 6 Ld µTDFN packages.
