∗1 Measured with a band width of 20 MHz.
∗2 Ensure that the HIGH signal of the CTL pin(pin 8)rises in less than 100µS to the level at which the output turns on.
3.3V
0V
Less than 100µS
∗3 When the HIGH signal is applied to the CTL pin , a current flows into the CTL pin for a short period until the output rises. Little current flows thereafter.
∗4 When the LOW signal is applied to the CTL pin to turn OFF the output, a current flows from the CTL pin for a short period until the output drops to 0V.
Ensure that the control circuit can sink this current.

Function
Output smoothing capacitor connection pin; connect a
low-impedance capacitor with a recommended
capacitance of 47µF between this pin and GND
Output pin; connect an output capacitor with a
recommended capacitance of 2.2µF between this pin
and GND
Test pin; use this internally connected pin in OPEN mode
Ground pin
Output ON/OFF control pin; output starts when the pin is
HIGH level, and stops at LOW level
Input pin; connect a low-impedance capacitor with a
recommended capacitance of 100µF between this pin
and GND
