RECOM Switching Regulator, 90° Pin,-40°C to +85°C Operating Temperature - R-78HB-0.5(L) Series - R-78HB3.3-0.5L


When you need to rein in a current supply that's too high for your electronic device, go for this switching regulator from RECOM. It takes a broad input voltage range between 9 and 72V DC and brings it down to a safe, lower level of 3.3V DC. The unit is pin-out compatible with linear regulators from the LM78XX range so you can dig out your legacy system and give it an upgrade. Thanks to its wide operating temperature range between -40°C and +85°C, this durable regulator is up to the challenge in harsh conditions.

• Maximum ripple and noise of 60mVp-p for reduced electrical interference
• Non-conductive plastic body helps prevent electric shocks
• Mean time between failures of 7,395,000 hours for long-term performance
• Efficiency rating of 76% for minimal heat waste
• Pins come at a 90°-angle to easily lay flat in spaces with limited height

Applications


• Telecommunications equipment
• Laptops and desktops
• Robotics systems
• Lighting fixtures

What size is this regulator?


This switching regulator has compact external dimensions of 11.5 (L) x 17.5 (W) x 8.5mm (D), so you'll find it easy to squeeze it onto your PCB.
