Self-Contained Inductor
Internal Short-Circuit Protection
Over-Temperature Protection
Fast Transient Response
Wide Input Range
The 78ST100 is a series of wide input
voltage, 3-terminal Integrated Switching
Regulators (ISRs). These ISRs have a maxi-
mum 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 short-
circuit and over-temperature protection, are
very flexible, and may be used in a wide
variety of applications.
