PINS FUNCTION
N. Name
Description
1 OUT Regulator Output.
2 SYNC Master/slave synchronization.
3 INH A logical signal (active high) disables the device. If INH not used the pin must be grounded.
When it is open an internal pull-up disable the device.
4 COMP E/A output for frequency compensation.
5 FB Feedback input. Connecting directly to this pin results in an output voltage of 1.23V. An external
resistive divider is required for higher output voltages.
6 VREF 3.3V VREF. No cap is requested for stability.
7 GND Ground.
8 VCC Unregulated DC input voltage.
