L4943 Overview

There are a total of 3 outputs supported by the voltage regulator. The rectifier regulator is packaged in Multiwatt-15 (Vertical, Bent and Staggered Leads) for ease of transportation. In Tube package, ready for shipping. The general voltage output of this power supply regulator is 3V~11V. Through Hole Universal mount allows for easy adaptation. The shunt regulator is intended for use in applications such as Converter, Car Audio System and others. It is recommended that the operating temperature be set to -40°C~85°C in order to prevent malfunctions. The input voltage for this external regulator is designed to be 11V~18V. It is possible to find 15terminals on the voltage regulator. The rectifier regulator's pinout begins with 15pins. Search L4943 to find more pin-to-pin solutions. A Through Hole is provided for mounting on PCBs or other boards. There are 15 pins on the power regulator. There should be 500mA output from the electrical regulator at the moment. A voltage greater than -600mVis required for this rectifier regulator. There is a quiescent current of 25mA in this alternator regulator.
