Pin Functions

PIN TYPE DESCRIPTION
NAME KC KTT NGN
ADJ 1 1 8 I Sets output voltage
ON/OFF 2 2 1 I Enable/Disable control
GND 3 3 2, 7 — Ground
IN 4 4 3 I Input supply
OUT 5 5 5 O Regulated output voltage. This pin requires an output capacitor to maintain stability. See the Detailed Design Procedure section for output capacitor details.
NC — — 4, 6 — No internal connection. Connect to GND or leave open.
