Output Trim Equations
Equation for calculating the trim resistor (in kΩ) given the desired adjusted voltage (Vadj) is shown below. The
Trim Up resistor should be connected between the Trim pin and Ground.
Equation for calculating the trim voltage (in V) given the desired adjusted voltage (Vadj) is shown below. The
Trim Up voltage should be connected between the Trim pin and Ground.
The SRBA-03A1AL modules feature an enable
pin with negative logic. If not using the enable
pin, leave the pin open (the module will be on).
During logic_high, the module is turned off,
during logic_low, the module is turned on. It inner
circuit impedance is showed as figure.
The SRBA-03A1A0 modules feature an enable
pin with Positive logic. If not using the enable pin,
leave the pin open (the module will be on).
During logic_high, the module is turned on,
during logic_low, the module is turned off. It inner
circuit impedance is showed as figure.
