Note : Dropout voltage is defined as the minimum differential voltage between and required to maintain regulation at. It is measured when the output voltage drops % below its nominal value. Note 3: Ground current is the regulator quiescent current plus the pass transistor current. The total current from the supply is the sum of the load current plus the ground pin current. Note : The specification applies for the junction temperature of 0 to +8C. PIN DESCRIPTIONS PIN # PIN SYMBOL PIN DESCRIPTION The input pin of the 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 drop out voltage during the load transient response. This pin must always be higher than by at least the amount of the dropout voltage and some margin in order for the device to regulate properly. 3 Gnd Adj (Adjustable Only) CBYP (Fixed Only) Ground pin. This pin must be connected to the lowest potential in the system and all other pins must be at higher potential with respect to this pin. able pin. A low signal or left open on this pin shuts down the output. This pin must be tied HI or to for normal operation. A resistor divider from this pin to the pin and ground sets the output voltage. To minimize the error due to the error amplifier, select the values of the resistor dividers to be less than 0Kς. A 70 to 000pF bypass capacitor connected to this pin reduces the output noise. The output of the regulator. A minimum of.µf with max ESR of ς capacitor must be connected from this pin to ground to insure stability. -PIN Output SOT-3 Voltage IRU0.V IRU0-8.8V IRU0-.V IRU0-8.8V IRU V IRU V IRU V Table - Nominal output voltage vs. part number.
