Recom Switching Regulator Through Hole Mount 3.3V DC Output Voltage 1A Output Current 3.3W Power R-78B3.3-1.0L

Recom R-78B3.3-1.0L is a high-performance switching regulator designed for through-hole mounting, providing a regulated 3.3V DC output voltage at a current of 1A, with a power rating of 3.3W. This compact switching regulator tolerates input voltages from 4.75V up to 32V DC, converting efficiently with approximately 89% efficiency and featuring low power dissipation of just 0.65W during operation.

The device offers continuous short-circuit protection with automatic recovery, protecting circuits from surges and faults. The robust design allows operation in a wide temperature range from -40°C to 85°C without requiring a heat sink, making it suitable for harsh industrial environments. Its compact SIP package measures 17.5mm in width, 11.5mm in length, and 8.5mm in depth, allowing neat PCB integration especially where space is limited.

Key electrical characteristics include ±0.4% line regulation, ±0.6% load regulation, and low output ripple and noise of 20mV peak-to-peak, ensuring stable output voltage under varying load and input conditions. The model includes three pins facilitating through-hole mounting, useful for easy and reliable installation.

With a mean time between failures (MTBF) exceeding 6.5 million hours, the R-78B3.3-1.0L guarantees long-term reliability in demanding applications. Typical use cases include manufacturing equipment, telecommunications hardware, and consumer electronics, where bundled voltage regulation and energy efficiency are critical.
