Low Power-Loss Voltage Regulators
PQ7RV4
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 than V
ref
MAX., and at the same time must be lower than
maximum rating 5V.
In OFF-state, the load current flows to RL from V
ADJ
through R
2
. Therefore the value of R
2
must be as high as possible.
In OFF state, as shown below,voltage
V
O
'=V
ADJ
X
R
L
/ (R
L
+R
2
)
occurs at the load. OFF-state equivalent circuit R
1
up to 5k
is allowed.
Select as high value of R
L
and R
2
as possible in thisrange. In some case, as output voltage is getting lower (V
O
<1V), impedance of load
resistance rises. In such condition, it is sometimes 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.
