... COMP COMP to provide capacitive load compensation. Applications Information Trimming the Output Voltage The MAX872/MAX874’s output voltage is trimmed for 0.2% tolerance at +25°C. If additional V desired, connect a potentiometer to TRIM, as shown in Figures 1a and 1b. Adjusting V OUT ry-trimmed voltage typically changes the output voltage tempco by 7ppm/°C per 100mV. ...
