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 VI in the range of 6 V < VI < 45 V to VQrated = 5.0 V. A

reset signal is generated for an output voltage of VQ < 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 µA to < 50 µA.
