FIGURE 7 - 90% EFFICIENT LINEAR REGULATOR

Output Voltage = 5V

Min (VIN-VOUT) 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 VREF .

R can be eliminated if the 200mA current limit on

SC

VOUT is adequate. Overall current limiting is

dependent upon PNP Beta. For greater accu-

racy, load currrent may be sensed in the ground

line.

CURRENT LIMITING AND REMOTE SHUTDOWN

Output Voltage = 5V

Max Output Current = 8A

Min VIN at No Load = 6.9V

Min VIN at 5A = 8.2V

Line Reg 10-30V = 3mV

Load Reg 0-5A = 17mV

Short Circuit Current = 1.8A

Note:

* 100Ω surge limiting resistor should be used for

output voltages above 8V.
