ILE4250G, ILE4250S
Low-power voltage repeater with ±0,5 % accuracy
with low drop voltage
(FUNCTIONAL EQUIVALENT OF TLE4250 INFINEON)
ILE4250G, ILE4250S - are integrated circuits of low-
power voltage repeater (adapter) with ±0,5 % accu-
racy, load capacity up to 50 mA and with low-drop
voltage. ICs realized in 5-pin plastic packages
ILE4250G - P-TO263-5-1, ILE4250S – P-TO220-5-
12.
Integrated circuits of low-power voltage repeater
(adapter) are purposed to transfer voltage with ±0,5
% accuracy (for load current 1…50mA) at a range of in-

P-TO263-5-1 package
put voltages from 6 to 28 V, with ±0,5 % accuracy (for
load current 1…10mA) at a range of input voltages
from 6 to 40 V, and with ±0,1 % accuracy (for load cur-
rent 1…10mA) at a range of input voltages from 6 to
16 V.
Drop voltage is less 0,3 at load current 10 mA. The
ICs are tolerant to over voltage of both polarities
(positive & negative). Adjustment pin input voltage
ICs is in range from 2 to 36 V
The ICs are used in power supply units of electronic
devices, especially in automotive electronics.
