Pin Name Description
1, 2 1 2 2 IN Supply Input.
7 2, TAB 5, 6, 7, 8 3, TAB GND Ground: SOT-223 Pin 2 and TAB are
internally connected. SOIC-8 Pins 5
through 8 are internally connected.
3, 4 3 3 4 OUT Regulator Output: Pins 3 and 4 must
be tied together.
5 — — — NC Not Connected.
8 — 1 1 EN Enable (Input): CMOS-compatible
control input. Logic-High = Enable;
Logic-Low = Shutdown.
— — 4 (Fixed) 5 (Fixed) BYP Reference Bypass: Connect external
470 pF capacitor to GND to reduce
output noise. Can be left open. For
1.8V or 2.5V operation, see Application
Information.
6 — 4 (Adjustable) 5 (Adjustable) ADJ Adjust (Input): Feedback input.
Connect to resistive voltage-divider
network.
EP — — — ePad Exposed Thermal Pad: Connect to
GND for best thermal performance.
