Functional Description

TLE 4267 is a 5-V low-drop voltage regulator in a

TO220-7 package. It supplies an output current of > 400 mA. The IC is shortcircuit-proof

and incorporates temperature protection that disables the IC at overtemperature.

Application

The IC regulates an input voltage

V

reset signal is generated for an output voltage

V

with an external capacitor. The device has two logic inputs. It is turned-ON by a voltage

of > 4 V on E2 by the ignition for example. It remains active as a function of the voltage

on E6, even if the voltage on E2 goes Low. This makes it possible to implement a self-

holding circuit without external components. When the device is turned-OFF, the output

voltage drops to 0 V and current consumption tends towards 0

µA.
