ILE4270

The IC regulates an input voltage in the range of 5.5 V < VI < 36 V to VQnom = 5.0 V. Up to 26 V it produces a regulated output current of more than 550 mA. Above 26 V the save-operating-area protection allows operation up to 36 V with a regulated output current of more than 300 mA. Overvoltage protection limits operation at 42 V. The overvoltage protection hysteresis restores operation if the input voltage has dropped below 36 V. A reset signal is generated for an output voltage of VQ < 4.5 V. The delay for power-on reset can be set externally with a capacitor.

Optimum reliability and life time are guaranteed if the junction temperature does not exceed 125 in operating mode. Operation at up to the maximum junction temperature of 150 is possible in principle. Note, however, that operation at the maximum permitted ratings could affect the reliability of the device.

This ILE4270 is a 5-V low-drop fixed-voltage regulator.

The maximum input voltage of the ILE4270 is 42 V (65 V, 400 ms). Up to an input voltage of 26 V and for an output current up to 550 mA it regulates the output voltage within a 2 % accuracy. The short circuit protection limits the output current of more than 650 mA.

The ILE4270 incorporates over voltage protection and temperature protection that disables the circuit at unpermissibly high temperatures.
