ILE4275G, ILE4275S
IC of low power voltage regulator 5V/400mA
with low drop voltage
(FUNCTIONAL EQUIVALENT OF TLE4275 INFINEON)
ILE4275G, ILE4275S - are integrated circuits of volt-
age regulator 5V/400 mA with low-drop voltage. ICs re-
alized in 5-pin plastic packages ILE4250G - P-TO263-
5-1, ILE4250S – P-TO220-5-12.
ICs of voltage regulator 5V/400 mA are purposed to
supply DC voltage 5V with 2% accuracy at a range of
input voltages from 5,6 to 40 V , with drop voltage 0,5V
at load current 300 mA. ICs are used in power supply
units of electronic devices, including automotive elec-
tronics. Maximum input voltage is 45 V. The ICs are
tolerant to over voltage of both polarities (positive &
negative), provide internal current limitation and output
voltage thermal shutdown. Reset function is available.
