Load
To set the output voltage for 3.1V or lower, use three OS capacitors
(different from the one written above).

Output ON = Open
Output OFF= Short
(0 to 0.5V)
C2=150µF(ESR=28m Ωor below) ×2 or more

- External Capacitors
C1 should be 330µF or higher and an of impedance 81mΩ
(20°C/ 100kHz) or below.
Recommend: Electrolytic Capacitor

- ON/OFF Control
ON/OFF is controlled by opening and shortening between
the 5pin(ON/OFF) and 3, 4pin (-Vin).
Be sure to maintain a slew rate of 0.03V/ µs or more
while the voltage is around 1V during start up and shut down.
- Adjustable Output Voltage
The output voltage is adjustable by connecting a resistor between
14pin (V.ADJ) and 17, 18pin (+Vout).
When 14pin is open, the following rated output voltage is as follows
Output = +3.3V±5%
