DESCRIPTION: The 78SR100 is a series of wide input voltage, 3-terminal Integrated Switching Regulators (ISRs). These ISRs have a maximum output current of 1.5A and an output voltage that is laser trimmed to a variety of industry standard voltages.

These 78 series regulators have excellent line and load regulation with internal shortcircuit and over-temperature protection, are very flexible, and may be used in a wide variety of applications.


FEATURES:
  • Very Small Footprint
  • High Efficiency > 85%
  • Self-Contained Inductor
  • Internal Short-Circuit Protection
  • Over-Temperature Protection
  • Wide Input Range
  • Voltage Input: 14.5-30VDC
  • Output: 12V at 1.5A
  • Power (Watts): 18W
  • Single Output
  • Type: Non-Isolated
  • Mounting Type: Through Hole, Right Angle

PIN-OUT INFORMATION:
