LT1931ES5#TRMPBF Overview
As a result of the use of the Cut Tape (CT) package, the performance of this voltage regulator is optimized. In this voltage regulator, there are a total of 5 terminations. There are two types of analog ICs in this voltage regulator 12v: SWITCHING REGULATOR ICs, which are the ones used in older voltage regulator 12vs. In order to save space, this harley voltage regulator is available in the SOT-23-5 Thin, TSOT-23-5 package. 1 outputs have been configured in the voltage regulator 12v. DC DC switching regulators like this one generate Adjustable outputs on their output pins to handle the power management. This voltage regulator 12v fits the Surface Mount mounting. Operating at 0°C~70°C TA is the recommended temperature for adjusting voltage regulator's operation. There is no dc to dc voltage regulator's minimum input voltage requirement for this regulator. According to the table below, DC DC switching regulator's output voltage (Min/Fixed) is equal to -1.255V. A maximum design flexibility is provided by the 1A output current of voltage regulator. Voltage regulator has a maximum input voltage of 16V. As a result of its peak reflow temperature, this voltage regulator is virtually indestructible. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 3V. DC DC switching regulator is part of the Switching Regulator or Controllers subcategory and can be found in the Switching Regulator or Controllers category. In the particular voltage regulators, the LT1931 family is represented. The voltage DC DC switching regulator can produce is -12V volts. During switching regulator operation, 5 pins are used. For this switching regulator, we recommend keeping the output voltage at at least -34V volts. Voltage regulator's maximal output current reaches 2A A to meet the operation requirements. The maximum output voltage of this regulator voltage is -5V. It is capable of maintaining high accuracy with the dc to dc voltage regulator's frequency of 1.2MHz.
