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/≤ 400 ms). The device can produce an output
current of more than 500 mA. 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 V_I in the range 6 < V_I < 35 V to V_Qnominal = 5.0 V. A reset
signal is generated for an output voltage of V_Q < 4.75 V. The reset delay can be set
externally with a capacitor. If the output current is reduced below 10 mA, the regulator
switches internally to standby and the reset generator is turned off. The standby current
drops to max. 700 µA.
