PIN TYPE(2) DESCRIPTION
NAME TO-263 TO-252 HTSSOP
(Legacy Chip)
GND 2 2 8 O Ground. Internally connected to heat sink.
IN 1 1 19 I Input power-supply voltage pin. For best transient response and to minimize input impedance, use the recommended value or larger ceramic capacitor from IN to ground. See the Recommended Operating Conditions table and the Input and Output Capacitor Selection section. Place the input capacitor as close to the input of the device as possible
NC — — 1-3, 5-7, 9-18, 20 — Not connected.
OUT 3 3 4 O Regulated output voltage pin. A capacitor is required from OUT to ground for stability. For best transient response, use the nominal recommended value or larger ceramic capacitor from OUT to ground. See the Recommended Operating Conditions table and the Input and Output Capacitor Selection section. Place the output capacitor as close to output of the device as possible.
(1) NC = No internal connection.
(2) I = input, O = output.
