LM78S40CN Product Details

LM78S40CN Overview

For optimal performance, this voltage regulator makes use of the Tube package. In this voltage regulator, there are a total of 16 terminations. There is one type of analog IC that this voltage regulator is equipped with, and that is the SWITCHING REGULATOR type. In order to save space, this harley voltage regulator is available in the 16-DIP (0.300, 7.62mm) package. There are 1 outputs configured on this voltage regulator 12v. There are output pins on this DC DC switching regulator that generate Adjustable output. Through Hole-mounting is compatible with this switching regulator. The operating temperature should be kept at 0°C~70°C TA when the voltage regulator 12v is in operation. This DC-DC switching regulator has a switching frequency of 100Hz~100kHz. As a result, the output voltage of the voltage regulator 12v (Min/Fixed) is 1.25V. It features maximum design flexibility due to dc to dc voltage regulator's 1.5A Switch output current. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 5V. There is a subcategory called Switching Regulator or Controllers that includes this voltage regulator. The LM78S40 family of DC/DC regulators includes this DC/DC regulator. The voltage DC DC switching regulator can produce is 40V volts. There are 16 pins that are used for the operation of the voltage regulator 12v. There should be at least a 2.5V volt output voltage for this switching regulator in order to make it work properly. The maximum output current reaches 1.5A A to meet the switching regulator operation requirements. Based on the maximal adjusting voltage regulator's output voltage of 40V Switch, adjusting voltage regulator can be operated easily. The maximum output voltage of this regulator voltage is 40V. A dc to dc voltage regulator's dc to dc voltage regulator's minimum supply voltage of 2.5V V ensures reliable performance. There is a maximum supply voltage of 40V at which DC DC switching regulator can operate.
