DESCRIPTION
The PT78HT200 is a series of fixed output, wide-input range, 3-terminal Integrated Switching Regulators (ISRs). These ISRs
have a maximum output current of 2A. The output voltage is also laser trimmed for high accuracy. Features include excellent
line and load regulation, internal short-circuit and over-temperature protection.
The PT78HT200 series is available in three package outlines, including horizontal SMD. Their small size and output voltage
selection makes these regulators ideal for use in a variety of applications.
