1 LOGIC REFERENCE Reference for Pin 81 Voltage Level. Connect to logic low supply. 2 −IN Inverting Input. 3 +IN Noninverting Input. 4 −VS Negative Supply Voltage. 5 CCOMP Compensation Capacitor. Tie to −VS. (See the Applications section for value.) 6 VOUT Output. 7 +VS Positive Supply Voltage. 8 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. Rev.
