ADI ADP123ACPZ-R7

正5.5V300mA

Overview

The ADP122/ADP123ACPZ-R7 are low quiescent current, low dropoutlinear regulators. They are designed to operate from an inputvoltage between 2.3 V and 5.5 V and to provide up to 300 mA of output current. The low 85 mV dropout voltage at a 300 mA loadimproves efficiency and allows operation over a wide inputvoltage range.

The ADP122/ADP123ACPZ-R7 have an internal soft start that gives aconstant start-up time of 350 μs. Short-circuit protection andthermal overload protection circuits prevent damage in adverse conditions. The ADP122/ADP123ACPZ-R7 are available in a tiny, 5-leadTSOT package and 6-lead LFCSP package for the smallestfootprint solution to meet a variety of portable applications.
