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.

Features

● Output voltage tolerance ≤ ± 2

● Low-drop voltage

● Very low standby current consumption

● Input voltage up to 40 V

● Overvoltage protection up to 60 V (≤ 400 ms)

● Reset function down to 1 V output voltage

● ESD protection up to 2000 V

● Adjustable reset time

● On/off logic

● Overtemperature protection

● Reverse polarity protection

● Short-circuit proof

● Wide temperature range

● Suitable for use in automotive electronics

Application

The IC regulates an input voltage VI in the range 5.5 V 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.
