ISL9014AIRNNZ-T 低压差稳压器

ISL9014AIRNNZ-T

Dual LDO with Low Noise, Low IQ, and High PSRR

低压差稳压器 W/ANNEAL LW NOISE HI PSRRLD 10LD 3X3 3 3V

ISLISL9014AIRNNZ-T 9014A is a high performance dual LDO capable of sourcing 300mA current from both outputs. The device has a low standby current and high-PSRR and is stable with output capacitance of 1μF to 10μF with ESR of up to 200m.

A reference bypass pin allows an external capacitor for adjusting a noise filter for low noise and high PSRR applications.
