TSR 3-1250A

TSR 3 models are non-isolated step down switching regulators. They can also be operated with negative output voltage. They come in a very compact open frame package of 15.5 x 9.4 x 6.2mm. The high efficiency admits a full load operation up to 50°C and up to 85°C with 50% current reduction. A low standby current, a very wider input range and no requirement for heatsink give these switching regulators a significant advantage over linear regulators. Together with a remote on/off input and protection against short circuit the TSR 3 series models are ideal point of load regulators for high reliable and energy critical applications.
