Description
1
OUT
Regulator Output.
2
SYNC
Master/Slave Synchronization. When it is open, a signal synchronous with the turn-off of the inter-
nal power is present at the pin. When connected to an external signal at a frequency higher than
the internal one, then the device is synchronized by the external signal.
Connecting together the SYNC pin of two devices, the one with the higher frequency works as
master and the other one, works as slave.
3
INH
A logical signal (active high) disables the device. With IHN higher than 2.2V the device is OFF and with
INH lower than 0.8V, the device is ON.
If INH is not used the pin must be grounded. When it is open, an internal pull-up disables the device.
4
COMP
E/A output to be used for frequency compensation.
5
FB
Stepdown feedback input. Connecting the output voltage directly to this pin results in an output
voltage of 1.235V. An external resistor divider is required for higher output voltages (the typical
value for the resistor connected between this pin and ground is 4.7K).
6

REF
Reference voltage of 3.3V. No filter capacitor is needed to stability.
7
GND
Ground.
