LP3875-ADJ - 1.5A Fast Ultra Low Dropout Linear Regulators

Download the LP3875-ADJ datasheet PDF. This datasheet also covers the LP3875ESX-ADJ variant, as both devices belong to the same 1.5a fast ultra low dropout linear regulators family and are provided as variant models within a single manufacturer datasheet.

General Description

The LP3875-ADJ fast ultra low-dropout linear regulators operate from a +2.5V to +7.0V input supply.

These ultra low dropout linear regulators respond very quickly to step changes in load, which makes them suitable for low voltage microprocessor applications.

Key Features

LP3875-ADJ 1.5A Fast Ultra Low Dropout Linear Regulators July 2005 LP3875-ADJ 1.5A Fast Ultra Low Dropout Linear Regulators General Description The LP3875-ADJ fast ultra low-dropout linear regulators operate from a +2.5V to +7.0V input supply. These ultra low dropout linear regulators respond very quickly to step changes in load, which makes them suitable for low voltage microprocessor applications. The LP3875-ADJ is developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3875-ADJ to operate under extremely low dropout conditions. Dropout Voltage: Ultra low dropout voltage; typically 38mV at 150mA load current and 380mV at 1.5A load current. Ground Pin Current: Typically 6mA at 1.5A load current.
