L4945 Datasheet | STMicroelectronics

® 5V VERY LOW DROP VOLTAGE REGULATOR 5V ± 4% PRECISE OUTPUT VOLTAGE OVER FULL TEMPERATURE RANGE (- 40 / 125 °C) VERY LOW VOLTAGE DROP (0.75Vmax) OVER FULL TEMPERATURE RANGE OUTPUT CURRENT UP TO 500mA OVERVOLTAGE AND REVERSE VOLTAGE PROTECTIONS REVERSE VOLTAGE PROTECTION SHORT CIRCUIT PROTECTION AND THERMAL SHUT-DOWN (with hysteresis) LOW START UP CURRENT DESCRIPTION The L4945 is a monolithic integrated circuit in Versawatt package specially designed to provide a stabilized supply voltage for automotive and industrial electronic systems. Thanks to their very low voltage drop, in automotive applications the devices can work correctly even during the crankBLOCK DIAGRAM TO220 ORDERING...
