L7981ATR Overview

This harley voltage regulator utilizes the Tape & Reel (TR) package for optimized performance. There are 8 terminations in this voltage regulator. This harley voltage regulator is available in the 8-SOIC (0.154, 3.90mm Width) Exposed Pad package for the purpose of space saving. DC DC switching regulator is configured with 1 outputs. This DC DC switching regulator generates Adjustable output on its output pins. This voltage regulator 12v fits the Surface Mount mounting. When operating, adjusting voltage regulator's operating temperature should be kept at -40°C~150°C TJ. The switching frequency of this DC-DC switching regulator reaches 250kHz~1MHz. This voltage regulator is able to operate with the minimal input voltage of 4.5V. DC DC switching regulator's output voltage (Min/Fixed) amounts to 0.6V. The peak reflow temperature of this regulator amounts to 260 to be essentially indestructible. Voltage regulator is designed to provide a nominal input voltage of 12V to meet the operation requirements. This voltage regulator is included in the Switching Regulator or Controllers subcategory. This DC/DC regulator belongs to the L7981 family. The adjusting voltage regulator's output voltage is maintain at 28V. 8 pins are used for switching regulator operation. The output voltage for this switching regulator should be kept at 600mV at least. Voltage regulator's maximal output current reaches 3A A to meet the operation requirements. It provides the adjusting voltage regulator's maximal output voltage of 28V. This DC-DC switching regulator operates from a supply voltage of 28V.
