TECHNICAL DATA
5-V Low-Drop Voltage Regulator
ILE4260-2
ILE 4260 is a 5-V low-drop fixed-voltage regulator in
P-TO220-5 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.
ILE4260S-2
Due to the wide temperature range of – 40 to 150 °C, the
ILE 4260 is also suitable for use in automotive applications.
The IC regulates an input voltage VI in the range
6 < VI < 35 V to VQnominal =5.0 V. A reset signal is generated
for an output voltage of VQ < 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.
