P-DSO-14-4

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.
