L4981B [STMicroelectronics]

L4981B Overview

In a 20-DIP (0.300, 7.62mm) package, it is available.In a Tube format, it is packaged.Through Hole is the device's mounting type.14.5V~19.5V should supply the voltage to it.-40°C~125°C is the operating frequency of the device.There are other IC types in this part, such as POWER FACTOR CONTROLLER.Several 20 terminals are present on the gadget.Startup current is 100?A.A component's pin number remains 20.Best part of the device has a L4981 in it.Switching occurs at a frequency of 100kHz.The 20 pins are summed up.I suppose it can be considered a subclass of Switching Regulator or Controllers.This device can continue to function accurately with a frequency of 80kHz.Through Hole mount includes it.Depending on the supply temperature, it will work with a maximum of 16mA.Several 1 outputs exist.12mA is the supply current for this gadget.Operation is possible with the 7.5V output.
