SD8916A

SHOUDING · DC-DC Converters · SOT-23-5

SD8916A from SHOUDING, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Power supply input, 2V to 6V range (absolute max 6.5V). Must be closely decoupled to GND with a 4.7µF or greater ceramic capacitor.
2 GND power_in Device ground. Return path for input/output capacitors and internal power MOSFETs.
3 EN input Chip enable. Drive above 1.5V to turn on the part; drive below 0.3V to shut down (<1µA shutdown current). Do not leave floating. Absolute max -0.3V to (VIN+0.3V).
4 FB input Output voltage feedback pin. Connected to an external resistor divider from VOUT; internal reference is 0.6V (VOUT = 0.6 × (1 + R1/R2)). For fixed-voltage variants (1.2/1.5/1.8/2.5/3.3V), tie directly to VOUT.
5 SW output Power switch output / inductor node. Connects to the drains of the internal P-ch and N-ch MOSFET switches. Route to external inductor; keep trace short and away from sensitive VOUT/FB nodes.
