LM78S40N Product Details

LM78S40N Overview


It is designed to provide optimal performance by utilizing the Tube package. There are 16 terminations in this harley voltage regulator. As this regulator voltage is equipped with an analog IC of the type SWITCHING REGULATOR, it is a SWITCHING REGULATOR-type voltage regulator. For space-saving purposes, this voltage regulator is available in the 16-DIP (0.300, 7.62mm) package. A total of 1 outputs are configured in this voltage regulator. On the output pins of this DC DC switching regulator, there is a Adjustable output generated. Through Hole-mount switching regulator. -40°C~125°C TA should be the operating temperature when voltage regulator is operating. Voltage regulator's switching frequency reaches 100Hz~100kHz. The voltage regulator can be operated with a voltage as low as 2.5V as an input voltage. According to the table below, DC DC switching regulator's output voltage (Min/Fixed) is equal to 1.25V. DC DC switching regulator's 1.5A Switch output current allows for maximum design flexibility. To meet the operation requirements, voltage regulator is designed to provide 5V as the nominal input voltage. The regulator voltage is included in the Switching Regulator or Controllers subcategory of voltage regulators. In this case, the DC/DC regulator belongs to the family LM78S40. Voltage can be produced at 40V volts by voltage regulator. The switching regulator operation of the system is controlled by 16 pins. In order to use this voltage regulator 12v at its full potential, the output voltage should be kept at at least 1.25V. A maximum output current of 1.5A A is available to meet the switching regulator operation requirements. On the basis of 40V Switch's maximal output voltage, DC DC switching regulator can be operated easily. The maximum voltage of voltage regulator 12v DC DC switching regulator can produce is 40V, which is the highest available.
