MAX638ACSA+ Overview
optimized performance is achieved by utilizing the Tube package in this voltage regulator. During the development of this harley voltage regulator, 8 terminations were made. A SWITCHING REGULATOR type of analog IC is equipped with this regulator voltage, which is the type of analog IC that is used in it. For space-saving purposes, this voltage regulator is available in the 8-SOIC (0.154, 3.90mm Width) package. There are 1 outputs configured on the voltage regulator. Adjusting voltage regulator's output pins generate Adjustable (Fixed) output. A Surface Mount mounting is required for this switching regulator. As long as its operating temperature is 0°C~70°C TA, dc to dc voltage regulator should perform well. This voltage regulator is able to operate with the minimal input voltage of 2.2V. In this adjusting voltage regulator, the output voltage (Min/Fixed) equates to 1.31V 5V. The peak reflow temperature of this regulator amounts to 260 to be essentially indestructible. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 12V. This voltage regulator is included in the Switching Regulator or Controllers subcategory. MAX638 is a family of voltage regulators that belong to the DC/DC industry. Voltage regulator is capable of giving voltage at 5V volts. To operate the voltage regulator 12v, 8 pins are required. There should be at least a 1.25V volt output voltage for this switching regulator in order to make it work properly. In order to meet the requirements of the switching regulator operation, the maximum output current reaches 75mA A. As a result, it is able to provide adjusting voltage regulator a maximum output voltage of 16V. DC-DC switching regulator with 16.5V supply voltage. The dc to dc voltage regulator's minimum supply voltage of 5V volts ensures reliable performance. DC DC switching regulator can be operated from a voltage of 16.5V as its maximum supply voltage. It is capable of maintaining high accuracy with the dc to dc voltage regulator's frequency of 65kHz. Normally, 75mA is the output current of adjusting voltage regulator.
