1V
OUT
Regulated Output Voltage

C1-
First Flying Capacitor: Negative Terminal

C1+
First Flying Capicitor: Positive terminal
4V
IN
Input Voltage. Recommended V
IN Range: 2.6V to 5.5V
5
POK
Power-OK Indicator: Output voltage sense. Open-drain NFET output. With an
external pull-up resistor tied to POK, V(POK) will be high when V
OUT is
regulating correctly. When V
OUT falls out of regulation, the internal open-drain
FET pulls the POK voltage low.
6
BATOK
Battery-OK Indicator: Input voltage sense. Open-drain NFET output. With an
external pull-up resistor tied to BATOK, V(BATOK) will be high when V
IN >
2.85V (typ). LM2797/98 pulls V(BATOK) low when V
IN < 2.65V (typ.) , and/or
when the part is in shutdown [V(EN) = 0].
