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 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.
