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. Features * Output voltage tolerance 53% (2% up to 50 mA) * Low-drop voltage * Current capability up to150 mA * Very low current consumption * Over temperature protection * Reverse polarity proof Short-circuit proof * Junction temperature -40 t +150 * Suitable for use in automotive electronics * Short-circuit proof Block Diagram
