Overview: ISL9021 NORTECROEMCOMMENMDEENDIDSELRD9E0PF2LO1AARCNEEMWENDTEPSAIGRNTS 250mA Single LDO with Low IQ, Low Noise and High PSRR LDO DATASHEET
FN6867 Rev 2.00 January 14, 2010 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 5m to 400m.
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. Pinouts ISL9021 (6 LD 1.6x1.6 µTDFN)
