  • High Efficiency > 85%
  • Wide Input Range
  • Self-Contained Inductor
  • Short-Circuit Protection
  • Over-T emperature Protection
  • Fast T ransient Response This is the new generation of the PT78HT200 Series wide input range 3 terminal regulators. These ISRs have a maximum output current of 2.0 Amps. The output voltage is laser trimmed for high accuracy. These 78 series regulators have excel- lent line and load regulation with internal short-circuit and over-temperature protec- tion, and are offered in a variety of standard output voltages. These ISRs are very flex- ible and may be used in a wide variety of applications.
