C1+

First Flying Capicitor: Positive terminal

4V

IN

Input Voltage. Recommended V

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

regulating correctly. When V

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

2.85V (typ). LM2797/98 pulls V(BATOK) low when V

when the part is in shutdown [V(EN) = 0].
