TC1262-3.3VDB

Microchip Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3

TC1262-3.3VDB from Microchip Tech, in a SOT-223-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Unregulated supply input; the datasheet specifies an input operating voltage of 2.7 V to 6.0 V and a 6.5 V absolute maximum input rating.
2 GND power_in Ground terminal; the SOT-223 tab is also GND per the package drawing and front view.
3 VOUT power_out Regulated voltage output, which requires a 1 µF minimum output capacitor to ground with an ESR greater than 0.1 Ω and less than 5 Ω.
