PIN DESCRIPTIONS

The descriptions of the pins are listed in Table 2-1.

TABLE 2-1:

PIN FUNCTION TABLE

Pin No.

(8-Pin MSOP,

PDIP, SOIC)

Symbol

Description

1

FC

Frequency control for internal oscillator, FC = open, FOSC = 10kHz typ; FC = V

+, F

OSC = 200kHz

typ; FC has no effect when OSC pin is driven externally.

2CAP+

Charge-pump capacitor, positive terminal.

3

GND

Power-supply ground input.

4CAP–

Charge-pump capacitor, negative terminal.

5

OUT

Output, negative voltage.

6

SHDN

Shutdown.

7

OSC

Oscillator control input. An external capacitor can be added to slow the oscillator. Take care to

minimize stray capacitance. An external oscillator also may be connected to overdrive OSC.

8V+

Power-supply positive voltage input.
