S-1206B25-M3T1U

ABLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

S-1206B25-M3T1U from ABLIC, in a SOT-23-3. 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 Input voltage pin. Operating range 1.7 V to 6.5 V (absolute max VSS + 7 V). Bypass to VSS with a ceramic capacitor of 0.1 µF or greater placed close to the pin.
2 VSS power_in Ground / negative supply reference pin for the regulator.
3 VOUT power_out Regulated output voltage pin. Fixed 2.5 V ±1.0% for the -B25 option, capable of sourcing up to 250 mA (subject to package power dissipation). Requires an output capacitor (CL ≥ 0.1 µF ceramic) between VOUT and VSS for phase compensation and stability.
