Pin Functions

PIN TYPE DESCRIPTION
NO. NAME
1 IN Input Voltage supply input
2 GND Ground Common ground
3 EN Input Shutdown input — disables the regulator when ≤ 0.4 V, enables the regulator when ≥ 1.15 V.
4 CAP Output Output capacitor connection. Internally connected to VOUT connection. This is the recommended device connection for the 1-µF output capacitor to ensure a stable output.
5 OUT Output Voltage output. Connect this output to the load circuit.
