    Products Detail

    ST1S12GR Overview


    A Tape & Reel (TR) package is used in this voltage regulator to optimize performance. In this voltage regulator, 5 terminations are present. 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. In order to save space, this voltage regulator is packaged in the SOT-23-5 Thin, TSOT-23-5 package. 1 outputs of voltage regulator are configured. Adjustable outputs are generated on the output pins of this adjusting voltage regulator. A voltage regulator 12v such as this one fits the Surface Mount mounting bracket. Keeping dc to dc voltage regulator's operating temperature at -40°C~125°C TJ is essential when operating. A DC-DC switching regulator such as this one switches at 1.7MHz. Voltage regulators like this one can operate at least with 2.5V as the dc to dc voltage regulator's minimum input voltage. It is evident from the table below that adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.6V. An input voltage of 3.6V is required to meet the requirements of the switching regulator operation. A voltage regulator 12v such as this falls under the Switching Regulator or Controllers category and belongs to this category. As a member of the ST1S12 family of DC/DC regulators, this is a DC/DC regulator. The voltage DC DC switching regulator can provide is up to 5V volts. During switching regulator operation, 5 pins are used. Ideally this switch regulator should have an output voltage of about 600mV at the very least. A maximum output current of 700mA A is provided to meet the switching regulator operation requirements. DC DC switching regulator offers a maximum output voltage of 5V as its maximum output voltage. DC-DC switching regulator with supply voltage 5.5V.
