Positive unregulated supply input for the regulator. Bypass to GND with at least 2.2μF capacitance having low
ESR for good transient response.

.
The output voltage can be set by two external resistors with the following relationship: V
1
= V
REF
* (1 + R1 / R2) + I
ADJ
* R1 where R1 is the resistor connected between V
1
and ADJ, and R2 is the resistor
connected between ADJ and GND.
Common terminal for ground reference.
The input and output bypass capacitors should be connected to this
pin. In addition the tab on the S-Pak package and pin 3 are also used for heat sinking the device.
Adjustable regulator output (Regulator #1) It is recommended to bypass to GND with at least 2.2uF. Size your
output capacitor to meet the transient loading requirement. If you have a very dynamic load, a lower ESR
capacitor will improve the response to these load steps.
Fixed regulator output (Regulator #2). It is recommended to bypass to GND with at least 2.2μF. Size your output
capacitor to meet the transient loading requirement. For dynamic loads, a lower ESR capacitor will improve the
response to these load steps.
