Availability: OutOfStock

概览

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 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.
