ADP165ACBZ-2.3-R7 低压差稳压器

ADP165ACBZ-2.3-R7

低压差稳压器 Low Iq LDO with Passthrough option

Very Low Quiescent Current,  150 mA, LDO Regulator

GENERAL DESCRIPTION ADP165ACBZ-2.3-R7

The ADP165/ADP166 are very low quiescent current, low

dropout (LDO), linear regulatorsthat operate from 2.2 V to 5.5 V

and provide up to 150 mA of output current. The low 120 mV

dropout voltage at a 150 mA load improves efficiency and allows

operation over a wide input voltage range.
