IKSEMICON ILE4264-2

TECHNICAL DATA
5-V/100MA LOW POWER LOW-DROP FIXED-VOLTAGE
REGULATOR WITH LOW CURRENT CONSUMPTION
The ILE 4264-2 is a monolithic integrated Low power
low-drop fixed voltage regulator 5-V/100mA with low
current consumption. The ILE 4264-2 is specially
designed to create power source with 5V output voltage,
loads up to 100 mA and drop voltage less than 0,5V. The
regulator is designed to supply electronic device in
automotive applications and some another applications.
The ILE 4264-2 is equipped with additional protection
against overvoltage of both polarities, load current
limitation, short-circuit and over temperature shutdown of
output voltage. The IC is supplied in chip (unpackaged)
form.

Thermal resistance junction ambient for IC with heat dissipater is calculated by formula:
Rth ja = Rth jc + Rth ca,
Rth jc - thermal resistance junction case, oC /W.
Application circuit and heat dissipater have to provide TJ ≤ 125 oС.
Maximum power Ptot,Вт, dissipated by IC for TA , is calculated by formula:
Ptot = (125 - TA) / Rth ja ,
125 – maximum permitable operating junction temperature, ОС
