TECHNICAL DATA
Low-Drop Voltage Regulator
ILE4276 is integrated circuit of voltage regulator
5V/400mA, 8.5V/400mA, 10V/400mA and adjustable with low
drop voltage.
The IC is purposed to supply DC voltages 5V, 8,5V,
10V and adjustable from 2,5 to 20 V with drop voltage less
0,5V, with load current 250 mA and low consumption current.
The IC is used in power supply units of electronic devices,
including automotive electronics. The IC is tolerant to over
voltage of both polarities (positive & negative), provide inter-
nal current limitation and output voltage thermal shutdown.
The IC realized in 5-pin plastic packages P-TO263-5-1 .
