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 m A. 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 < µA.

Frequently Asked Questions
What output capacitor is recommended for stable operation?
Stability requires using a 22 mF or larger output capacitor with an ESR of less than or equal to 3 Ω.
How can I temporarily switch off the voltage regulator IC?
The device incorporates an INH (Inhibit) pin, which accepts a TTL-compatible, low-active signal to switch the IC off.
What protection mechanisms are built into the TLE 4263 regulators?
It features integrated protections against overload, overtemperature, reverse polarity, and short circuits.
