LK115D33-TR Product Details

LK115D33-TR Overview


An Tape & Reel (TR) case is included with the delivery. There is a 8-SOIC (0.154, 3.90mm Width) case with the integrated voltage regulator. There are 8 terminations on the battery regulator IC chip and each of them has its own function. In terms of output type, Fixed is what the Regulator IC produces. The electronic component implements 1 Voltage regulator ICs. IC Regulator is possible to alter the range of the operating temperature of Surface Mount in the device. In order for this IC voltage regulator to operate, the temperature has to be kept at -40°C~125°C degrees. In this case, the output function that is configured for this regulator IC is Positive. It has a total of 8 pins on IC voltage regulator. In order to ensure prompt, adequate, and prompt performance, this regulator has 1 outputs in total. In terms of its dropout voltage, it is 10 volts. There are 8 pins on the chip. It is LK115 for this regulator, just for your information. In order to pack the regulator, the method is TAPE AND REEL. In order to meet the operating requirements of the regulator, its maximal output current reaches 100mA. It operates in the 3mA Quiescent Current state. The top supply voltage is 20V volts.
