MAX1977EEI+ Product Details

MAX1977EEI+ Overview


It supports 4 outputs in total. To facilitate transportation, alternator regulator is packaged in 28-SSOP (0.154, 3.90mm Width). Ready for shipping in Tube package. In general, this voltage controller outputs a voltage of 3.3V 5V 2V~5.5V. It has a mounting type of Surface Mount. Applications targeting this shunt regulator include Controller, Notebook Power System and others. In order to avoid malfunctions, the operating temperature should be set to 0°C~85°C. This external regulator requires a voltage input of 4.5V~24V. You can find 28 terminals of the voltage regulator. It has received a great deal of support as a DUAL SWITCHING CONTROLLER regulator. Assuming that the rectifier regulator has 28 pins, the pinout begins from there.
