This Recom DC to DC Single Output converter is from the R-78Bxx-1.5L series. The switching regulator is ideally suited to replace the 1A 78xx linear regulators and is pin compatible. The convertor has a high voltage input range, and an efficiency of up to 97%, meaning that very little energy is wasted as heat, so there is no need for any heat sinks with their additional space. The L-Version with 90° pins allows direct replacement for laid-flat regulators where component height is at a premium. The low ripple and noise figures, and a short circuit input current of typically only 15mA, round off the specifications of this versatile converter series. Typical applications include telecommunication, automotive, industrial, aerospace and battery powered applications. * Accuracy: 2% * Grid pitch: 2.54 mm * Material: UL94-VO * Low ripple and noise * Fully certified to EMC standards * Output current: 1.5A * Output voltage: 3.3V DC * Specification: SIP3 * Efficiency: 82% * Operating Temperature from -40°C to +85°C * 'L' Version with 90° pins * Dimensions: 11.5(L) x 7.5(W) x 10.2(H)mm * Type: DC to DC Converter R-78Bxx-1.5 (L) Series * Manufacturer's part: R-78B3.3-1.5L https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2025-01-22 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2025-04-16 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2025-05-18 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2025-06-25 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2025-08-03 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2025-08-24 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2025-10-05 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2026-03-12 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2026-05-20 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2026-06-12 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2026-07-05 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2026-07-28 https://elecena.pl/product/27732938/recom-80099151-r-78b3-3-1-5l-dc-dc-converter-4-75-18v-in-3-3v-out-bent-pins 2026-08-21
