L5989D Product Details

L5989D Overview

Using the Tube package, this voltage regulator optimizes the performance of the voltage regulator 12v. There are 16 terminations in this voltage regulator. As a matter of fact, the type of analog IC that this voltage regulator 12v is equipped with is called SWITCHING REGULATOR. The harley voltage regulator is available as a 16-TSSOP (0.173, 4.40mm Width) Exposed Pad package to save space. DC DC switching regulator is configured with 1 outputs. Adjustable outputs are generated on the output pins of this adjusting voltage regulator. Switching regulators like this one can be mounted on the Surface Mount mounting system. Keeping dc to dc voltage regulator's operating temperature at -40°C~150°C TJ is essential when operating. A DC-DC switching regulator of this type operates at a switching frequency of 100kHz~1MHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 2.9V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.6V. The maximum input voltage of voltage regulator is 18V. A regulator voltage's peak reflow temperature amounts to 260 being indestructible. An input voltage of 12V is required to meet the requirements of the switching regulator operation. DC DC switching regulator is part of the Switching Regulator or Controllers subcategory and can be found in the Switching Regulator or Controllers category. This DC/DC regulator belongs to the L5989 family. Voltage can be produced at 18V volts by voltage regulator. To operate the voltage regulator 12v, 16 pins are required. In order to meet the requirements of the switching regulator operation, the maximum output current reaches 4A A.
