Voltage Regulators - DC DC Switching Regulators

switching regulatoruniversal regulator subsystem16-lead DIP1.5 A peak switch

LM78S40CN/NOPB is a 16-lead universal switching regulator subsystem for adjustable step-down, step-up, and inverting power supplies.

Best for

  • Low-part-count switching regulator designs
  • Battery-operated power systems
  • Step-down, step-up, and inverting converters

Avoid if

  • The design requires a modern integrated switching regulator with verified lifecycle or compliance data
  • The application exceeds the 40 V or 1.5 A internal switch ratings

Check before use

  • Commercial operating-temperature range
  • External diode requirements at higher output current
  • Thermal dissipation and package limitations
