5-V Low Drop Voltage Regulator
Features
Functional Description
TLE 4263 is a 5-V low drop voltage regulator in a SMD
package
PG-DSO-8-16. The maximum input voltage is 45 V. The
maximum output current is more than 200 mA. The IC is
short-circuit
protection which turns off the IC at overtemperature.
The IC regulates an input voltage
V
an output voltage of
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.
