LM21305SQ/NOPB Overview


For optimal performance, this voltage regulator makes use of the Tape & Reel (TR) package. There are 28 terminations in this harley voltage regulator. A SWITCHING REGULATOR analog IC is used in this voltage regulator 12v, which is the type of analog IC that this voltage regulator 12v is equipped with. The harley voltage regulator is available as a 28-WFQFN Exposed Pad package to save space. There are 1 outputs configured on the voltage regulator. On the output pins of this DC DC switching regulator, there is a Adjustable output generated. The voltage regulator 12v fits the Surface Mount mounting hole. As long as its operating temperature is -40°C~85°C TA, dc to dc voltage regulator should perform well. 300kHz~1.5MHz is the switching frequency of this DC-DC switching regulator. This voltage regulator is able to operate with the minimal input voltage of 3V. In this adjusting voltage regulator, the output voltage (Min/Fixed) equates to 0.598V. There is a voltage regulator maximum input voltage of 18V. Due to its 260 high peak reflow temperature, this voltage regulator 12v is virtually indestructible. To meet the operation requirements, voltage regulator is designed to provide 12V as the nominal input voltage. There is a subcategory called Switching Regulator or Controllers that includes this voltage regulator. There is a DC/DC regulator in this family that belongs to the LM21305 family. The adjusting voltage regulator's output voltage is maintain at 5V. The switching regulator operation of the system is controlled by 28 pins. Ideally this switch regulator should have an output voltage of about 600mV at the very least. For switching regulator maximum operation, dc to dc voltage regulator delivers 5A A. Without external influences, harley voltage regulator consumes 9mAA of quiescent current.
