, Low Noise and
High PSRR LDO in Tiny
4 Ball WLCSP Package
(0.975x1.155mm)
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 5mΩ to 400mΩ.
The input voltage range for the ISL9021A is between
1.5V to 5.5V and the output voltage comes in many
fi xed voltage options with ±1.8% accuracy over-
temperature, line and load ranges. The ISL9021A has
typical PSRR of 75dB @ 10kHz and 50dB @ 1MHz.
