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 57
volts using external resistors.

Notes:
1. Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used.
Changes in output voltage due to heating effects must be taken into account separately.
2. If not tested, shall be guaranteed to the specified limits.
3. The • denotes the specifications which apply over the full operating temperature range.

STANDARD APPLICATION
* 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.
