The P78W-500R series is a family of compact non-isolated DC-DC converters designed to offer a high performance alternative to linear regulators. Housed in a compact 3-pin SIP package, this series is pin compatible with LM78XX model regulators, and features a wide input voltage range. Additionally, the P78W-500R does not require a heat sink, making it ideal for applications where board space is at a premium and energy efficiency is a concern.
