at 5A = 8.2V
Line Reg 10-30V = 3mV
Load Reg 0-5A = 17mV
Short Circuit Current = 1.8A
Note:
* 100
surge limiting resistor should be used for
output voltages above 8V.
Output Voltage = 5V
Min (V

) at 2A = 0.4V
Load Reg 0-2A = 20mV
Max Output Current = 3A
Line Reg 6-30V = 10 mV
Notes:
For output voltages above 8V and load currents
which allow PNP base current to be limited to
25mA, the internal zener may be used, eliminat-
ing the need for the two external diodes and the
divider on V
REF
.
R
SC
can be eliminated if the 200mA current limit on
V
is adequate. Overall current limiting is
dependent upon PNP Beta. For greater accu-
racy, load currrent may be sensed in the ground
line.
