Explanation of the Terminal
No.
Symbol
Function
1
C-
Capacitance connection terminal for charge pump.
2
V_IN
Power supply terminal.
3
C+ Capacitance connection terminal for charge pump.
4
V_OUT Output terminal.
5
GND GND terminal.
Logic input terminal.
“H” input on this pin enables the IC to operate while “L” input causes it to shut down.
6
SHDN The behavior of the IC is unpredictable if the input on the pin is undefined. Ensure that the
pin is tied to either “H” or “L” level.
In the condition of V_IN = 2.7V or less, please make it to "L" level.
