PT78HT205H datasheet



The PT78HT205H 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.


1. High Efficiency: Up to 90%

2. Wide Input Range

3. Self-Contained Inductor

4. Short-Circuit Protection

5. Over-Temperature Protection

6. Fast Transient Response
