DESCRIPTION

The R-78HB3.3-0.5 is a high-efficiency DC/DC switching regulator designed to deliver a stable 3.3V output at up to 0.5A. It operates over a very wide input voltage range of 9V to 72V DC, making it highly versatile. With an efficiency of up to 82%, it minimizes heat generation and often eliminates the need for a heatsink. The device provides a clean output with low ripple and noise (typically 20mVp-p) and includes continuous short-circuit protection and thermal shutdown. Its standard SIP3 package is pin-compatible with older LM78xx linear regulators, offering an easy upgrade path for industrial, telecommunication, and battery-powered applications.
