Name
Pin Function
OUTB Output for LDOB
VIN Input supply voltage terminal
OUTA Output for LDOA
FBA
GND
Feedback sense pin for LDOA — Connect this pin to an
external resistor divider to set V
OUTA
Analog and digital ground
Logic input — active HIGH enables both LDOs for the SC560A and
EN
SC560C, or LDOA for all other variants. EN must be active in the
SC560B and the fixed output variants before ENB can be activated.
BYP LDO bypass output — Bypass with a 22nF capacitor
ENB
PGOOD
Logic input — active HIGH enables LDOB for SC560B and the fixed
voltage variants.
Power Good output — monitors the level of LDOA, switches low
when the output drops out of regulation.
Feedback sense pin for LDOB — Connect this pin to an external
FBB
resistor divider to set V
OUTB
