Very low drop voltage regulators with inhibit function

Features

■ Very low dropout voltage (0.15 V typ. at 10 mA

load)

■ Low quiescent current (typ. 2.5 mA, at 100 mA

load)

■ Output current up to 100 mA

■ Adjustable (from VOUT = 2.5 V only SO-8) and

fixed (3.3 V and 5 V) output voltage version

■ Internal current and thermal limit

■ Load dump protection up to 60 V

■ Reverse transient protection up to -50 V

■ Temperature range: -40 to 125 °C

■ Package available: TO-92, DPAK, SO-8 (with

inhibit control)

Description

The LM2931xx are very low drop regulators. The

very low drop voltage and the low quiescent

current make them particular suitable for low

noise, low power applications and in battery-

powered systems. In the 8-pin configuration (SO-

8), fully compatible with the older L78Lxx family, a

shutdown logic control function is available.

This means that when the device is used as a

local regulator it is possible to put a part of the

board in standby, decreasing total power

consumption. Ideal for automotive applications,

LM2931xx is protected from reverse battery

installations or 2 battery jumps. During the

transient, such as a 60 V load dump, when the

input voltage can exceed the specified maximum

operating input voltage of 26 V, the regulator

automatically shuts down to protect both internal

circuitry and the load.
