Functional Description TLE 4262 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 with a capacitor. The IC can be switched off via the inhibit input, which causes the current consumption to drop from 720 µA to < µA.

Frequently Asked Questions
What input and output capacitors are required for stable operation?
An input capacitor C requires a series resistor (approx. 1W), and the output capacitor must be at least 22mF with an ESR of no more than 3Ω.
Are there built-in protective features on this IC?
Yes, it includes overtemperature protection, reverse polarity protection, short-circuit proof capability, and low-drop voltage regulation.
How can I adjust the reset signal threshold?
The reset threshold (SRES) can be adjusted by connecting a voltage divider from the output to ground at Pin 10.
What is the standard operating input voltage range?
The regulator operates on an input voltage V in the range of 6 V to 45 V, and targets a regulated output of 5.0 V.
