TLE4263GSXUMA2

The OPTIREG Linear TLE4263 is a 5 V low drop voltage regulator in a SMD package PG-DSO-14, PG-DSO-20, or PG-DSO-8. The maximum input voltage is 45 V. The maximum output current is 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 V₁ in the range between 6 V and 45 V to an output voltage to V₀,nom = 5.0 V. A reset signal is generated for an output voltage of VQ,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 μA to typical 0 μA.
