Application Information Controlling the short circuit current to the minimum necessary for a given application maximizes device protection and reliability. Approximate values for the current limiting resistors can be determined from the equation: RCL = ((0.65/ISC) - 0.01) where ISC is the short circuit current limit in amperes at TC = 25C. Current limits for positive and negative load currents can be set independently. Current limiting resistors carry the full output current, therefore the short circuit current limit should be used in determining resistor wattage. Lead lengths of the limiting resistors should be minimized and highly inductive resistor types should be avoided. Large bypass capacitors are recommended across the power supply terminals if the application requires large output current transients. Care should be taken to keep the power supply ground currents from flowing through the signal ground path.
