Functional Description
TLE 4263 G is a 5-V low-drop voltage regulator in a P-DSO-20-6 SMD package. The
maximum input voltage is 45 V. The maximum output current is more than 200 mA. The
IC is short-circuit proof and incorporates temperature protection that disables the IC at
overtemperature.
The IC regulates an input voltage

in the range of 6 V <

< 45 V to

Qrated
= 5.0 V. A
reset signal is generated for an output voltage of

< 4.5 V. This voltage threshold can
be decreased to 3.5 V by external connection. The reset delay can be set externally by
a capacitor. The integrated watchdog logic controls the connected microcontroller. The
IC can be switched off via the inhibit input, which causes the current consumption to drop
from 800
