G5M1119 Page: 2/4 ISSUED DATE :2005/11/28 REVISED DATE : Pin Descriptions Name Pin# Function GND 1 Ground Vout 2 The output of the regulator. A minimum of 10F capacitor must be connected from this pin to ground to insure stability. Vin 3 The input pin of regulator. Typically a large storage capacitor is connected from this pin to ground to insure that the input voltage does not sag below the minimum dropout voltage during the load transient response .This pin must always be 1.3V higher than Vout in order for the device to regulate properly. EN 5 The input pin of regulator. TTL/COMS compatible input Logic high=disable output, Logic Low or open= Enable output. (internal Pull-down resistor~100k).

G5M1119 Page: 3/4 ISSUED DATE :2005/11/28 REVISED DATE : JA Thermal Resistance Junction– to-Ambient(No heat sink ;No air flow) - 300 - :/w JC Thermal Resistance Junction-to-Case Control Circuitry/Power Transistor - 100 - /w: Note 1: See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead =1/18” from the package. Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 5W. Power dissipation is determined by the input/output difference and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range. Note 3: Quiescent current is defined as the minimum output current required in maintaining regulation. At 12V input/output differential the device is guaranteed to regulate if the output current is greater than 10mA.
