Note 2: Dropout voltage is defined as the minimum differential voltage between VIN and VOUT required to maintain regulation at VOUT. It is measured when the output voltage drops 1% 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. PIN DESCRIPTIONS 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 VIN drop out voltage during the load transient response. This pin must always be higher than VOUT by at least the amount of the dropout voltage and some margin in order for the device to regulate properly. GND EN Adj (Adjustable only) CBYP (Fixed only) VOUT 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. Enable pin. A low signal or left open on this pin shuts down the output. This pin must be tied HI or to VIN for normal operation. A resistor divider from this pin to the VOUT pin and ground sets the output voltage. A 470 to 1000pF bypass capacitor connected to this pin reduces the output noise. The output of the regulator. A minimum of 2.2uF with max ESR of 1 capacitor must be connected from this pin to ground to insure stability. 3 Advanced Power Electronics Corp.
