Renesas ISL9021AIRUFZ-T7A

正5.5V250mA

Overview

The ISL9021AIRUFZ-T7A 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 ISL9021AIRUFZ-T7A 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 ISL9021AIRUFZ-T7A 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 ISL9021AIRUFZ-T7A is offered in tiny 4-bump 1.155mmx0.975mm WLCSP and 1.6mmx1.6mm 6 Ld µTDFN packages.
