1. Standby function
1) The power can be turned on or off by
making pin 5 (standby terminal) high
or low.
2) The standby terminal has threshold
voltage of approx. 2.1 V, however, it
has temperature dependency of
approx.
−
6 mV/°C. The recommended

range of use is shown in table 1.
3) The internal circuit of standby terminal is as shown in figure 1. When the standby terminal is high, the current
approximately expressed by the following equation will flow into the circuit.
