Functional Description
P-TO220-7-230
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

of < 4.5 V. The reset delay can be set
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.
