LR1107/E; At normal operation, SD must be tied to VDD through a 10KΩ pull up resistor.

ERROR

Error flag, active low; when the output dropout of regulation due to low input voltage, the

(for LR1107E)

LR1107E produces a logic low signal at the ERROR pin.

SET/ADJ

(for LR1107)

O Voltage-Setting Input. Connect an external resistive voltage-divider from VOUT to this pin to

set the output voltage.
