Functional Description TLE 4260; S is a 5-V low-drop fixed-voltage regulator in a P-TO220-5-H/S package. The
maximum input voltage is 42 V (65 V/≤ ms). The device can produce an output
current of more than 500 m A. It is shortcircuit-proof and incorporates temperature protection that disables the circuit at unpermissibly high temperatures. Due to the wide temperature range of – 40 to 150 °C, the TLE 4260; S is also suitable for use in automotive applications.
The IC regulates an input voltage VI in the range 6 < VI < 35 V to VQnominal = 5.0 V. A reset signal is generated for an output voltage of VQ < 4.75 V. The reset delay can be set
externally with a capacitor. If the output current is reduced below 10 m A, the regulator switches internally to standby and the reset generator is turned off. The standby current drops to max. 700 µA.

Frequently Asked Questions
Is the TLE 4260 suitable for automotive use?
Yes, it supports a wide temperature range of –40 to 150 °C and is short-circuit proof, making it suitable for automotive electronics.
What protections does this IC incorporate?
It includes internal protection against overload, overvoltage, overtemperature, reverse polarity, and saturation.
What happens when the output current drops significantly?
If the output current is reduced below 10 mA, the regulator switches internally to a standby mode and turns off the reset generator.
Does the device generate a low voltage warning signal?
Yes, a reset signal (Q) is generated if the output voltage falls below 4.75 V.
