When Tj exceeds 150℃, the internal circuit cuts off the output. (Vin=-10V, Iout=500mA, Cin=2μF, Cout=1μF; Tj=0℃ to 125℃, unless otherwise specified.) CHARACTERISTIC SYMBOL TEST CIRCUIT CONDITION MIN.

STANDARD APPLICATION A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0 V more negative even during the high point on the input ripple voltage. XX = these two digits of the type number indicate voltage. * = Cin is required if regulator is located an appreciable distance from power supply filter. ** = Co improves stability and transient response.
