FUNCTION

Regulated output voltage ± 3.0%.

Supply Voltage to the IC.

CMOS compatible input lead. The Watchdog function

monitors the falling edge of the incoming signal.

Ground connection.

CMOS compatible output consisting of a continuously

generated signal used to “wake up” the microprocessor

from sleep mode.

CMOS compatible output lead RESET goes low whenever

VOUT drops by more than 7.0% from nominal, or during the

absence of a correct Watchdog signal.

Buffered bandgap voltage used to create timing current for

RESET and Wakeup from RDelay.

No Connection.

Kelvin connection which allows remote sensing of the

output voltage for improved regulation. Connect to VOUT if

remote sensing is not required.

Connect to Ground potential or leave unconnected.
