DESCRIPTION
These three terminal positive regulators are supplied in hermetically sealed
packages. All protective features are designed into the circuit, including thermal
shutdown, current-limiting, and safe-area control. With heat sinking, these devices
can deliver up to 1.5 amps of output current. The LCC-20 device is limited to .5
amps. The unit also features output voltages that can be fixed from 1.2 volts to 37
volts using external resistors.

APPLICATION
Vout
Vin
* Cin is required if regulator is located an
appreciable distance from power supply filter.
** Co is not needed for stability, however it does
improve transient response.
R
Vout = 1.25 V (1 + 2 )+ IAd j R2
R1
Since IAdj is controlled to less than 100 µA,
the error associated with this term is negligible
in most applications.
