Functional Description
TLE 4263 is a 5-V low-drop voltage regulator in a P-DSO-14-8 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 which turns off the IC at
overtemperature.
The IC regulates an input voltage
V
I
in the range of 6 V <
V
I
< 45 V to
V
Q,nom
= 5.0 V. A
reset signal is generated for an output voltage of
V
Q,rt
< 4.5 V. This voltage threshold can
be decreased to 3.5 V by external connection of a voltage divider. The reset delay can
be set externally by a capacitor. The integrated watchdog logic supervises the connected
microcontroller. The IC can be switched off via the inhibit input, which causes the current
consumption to drop from 900 A to typical 0 A.
