Low Power-Loss Voltage Regulators

ON/OFF operation is available by mounting externally D
2
and R
3
.
When V
ADJ
is forcibly raised above V
ref
(1.25V TYP) by applying the external signal, the output is turned off (pass transistor of
regulator is turned off). When the output is OFF, V
ADJ
must be higher then V
ref
MAX., and at the same time must be lower than
maximum rating 7V.
In OFF-state, the load current flows to R
L
from V
ADJ
through R
2
. Therefore the value of R
2
must be as high as possible.
V

)
occurs at the load. OFF-state equivalent circuit R
1
up to 10
is allowed. Select as high value of R
L
and R
2
as possible in this range.
In some case, as output voltage is getting lower (V
O
<1V) , impedance of load resistance rises. In such condition, it is sometime
impossible to obtain the minimum value of V
O
'. So add the dummy resistance indicated by R
D
in the figure to the circuit parallel to
the load.

From V

Assuming that V

Next, assuming that V
