Description

LOGIC REFERENCE

Reference for Pin 81 Voltage Level. Connect to logic low supply.

−IN

Inverting Input.

+IN

Noninverting Input.

−VS

Negative Supply Voltage.

CCOMP

Compensation Capacitor. Tie to −VS. (See the Applications section for value.)

VOUT

Output.

+VS

Positive Supply Voltage.

DISABLE

Disable, Active Low.

1 When Pin 8 (DISABLE) is higher than Pin 1 (LOGIC REFERENCE) by approximately 2 V or more, the part is enabled. When Pin 8 is brought down to within about 1.5 V of

Pin 1, the part is disabled. (See the Specifications tables for exact disable and enable voltage levels.) If the disable feature is not going to be used, Pin 8 can be tied to

+VS or a logic high source, and Pin 1 can be tied to ground or logic low. Alternatively, if Pin 1 and Pin 8 are not connected, the part is in an enabled state.
