SHDN
Positive terminal for the first charge pump capacitor
Negative terminal for the second charge pump capacitor
Positive terminal for the second charge pump capacitor
Supply voltage
12V output voltage VOUT = VCC when in shutdown mode
Ground
Active high C-MOS logic level shutdown input. SHDN is internally pulled up to VCC.
Connect to GND for normal operation. In Shutdown mode the charge pumps are turned
off and VOUT = VCC
