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 TLE 4263 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 TLE 4263 can be switched off via the inhibit input, which causes the current consumption to drop from 800 mA to < 50 mA.
