RECOM Switching Regulator, ±0.4% Line Regulation, 90° Pins - R-78B-1.0(L) Series - R-78B3.3-1.0L

To set up a reliable power supply that keeps your circuit ticking along, pick this switching regulator from RECOM. It accepts inputs between 4.75 and 32V DC, which it converts to 3.3V DC outputs in a snap. As it features continuous short-circuit protection with automatic recovery, it stops surges in their tracks to protect sensitive devices. Thanks to a mean time between failures of 6,584,000 hours, you can rest easy knowing this mini powerhouse will deliver top-notch performance in the long term.

• Through-hole mounting for quick and simple installation
• Wide operating temperature range between -40°C and +85°C without a heat sink, so suits challenging conditions
• Compact dimensions of 17.5 (W) x 11.5 (L) x 8.5mm (D) to fit neatly onto a busy PCB
• Internal power dissipation of just 0.65W during operation, meaning it's an energy-efficient choice

Applications

• Manufacturing industry
• Telecommunications equipment
• Consumer electronics

When should I use a switching regulator with 90° pins?

Switching regulators with 90° pins, like this one, are fitted flush against the circuit board, making them ideal for setups with limited space.
