| TECHNICAL DATA Power Voltage Regulator 5 V/500mA with Low Drop-out Voltage (analog to TLE4260 -2, Siemens) ILE4260-2 (analog to TLE4260-2, Siemens) - single-chip integrated IC of power voltage regulator 5V/500 mA with low drop-out voltage implemented in 5-pin 220AB/5 with external radiator. IC of power voltage regulator 5V/500mA is designed for creation of constant voltage of 5V with drop-out voltage less than 0.5V and load current up to 500 mA and used in electronic equipment power supplies. IC has protection against overvoltage of both positive and negative polarity, has internal limiting of maximum load current with temperature reset of output voltage. ILE4260-2 ILE4260-2 ILE 4260-2 P-TO220-5-2 TA = -40 / 125 C Features: * * * * * * * * * * High precision of output voltage 5V 2% Low drop-out voltage Low consumption current Low starting consumption current Overheat embedded protection Protection against outputs reversed polarity Input voltage up to 42V Internal limiting of maximum load current with temperture output voltage reset Overvoltage protection (input voltage more than 42 V) Chip temperature range from - 40 to +125.
