ELECTRICAL SPECIFICATIONS
Unless otherwise specified, these specifications apply over CIN=CO=2.2F, IO=100uA, VIN(MIN)=4.5V, CBYP=470pF
(for fixed voltage devices), VEN=2V and TA=25oC. Typical values refer to TA=25oC. Low duty cycle pulse testing is used
which keeps junction and case temperatures equal to the ambient temperature.

Note 1: Low duty cycle pulse testing with Kelvin connections is required in order to maintain accurate data.
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
VIN
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 VOUT by at least the amount of the dropout voltage and some margin in order
for the device to regulate properly.
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.
GND
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.
EN
Adj (Adjustable only)
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 1Ω capacitor
must be connected from this pin to ground to insure stability.
