TC1071VCT713 from Microchip Tech, 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 | Unregulated supply input. Operating range 2.7 V to 6.0 V (absolute max 6.5 V). Bypass to GND with a 1 µF capacitor if more than 10 inches of wire separates the regulator from the source. |
| 2 | GND | power_in | Ground terminal / reference for the regulator and the R1/R2 output-set divider. |
| 3 | SHDN | input | Active-low shutdown control input. Regulator is fully enabled when a logic high (V_IH ≥ 45% of V_IN) is applied and enters shutdown when a logic low (V_IL ≤ 15% of V_IN) is applied. In shutdown, V_OUT falls to zero and supply current drops to 0.5 µA (max). Tie to VIN if the shutdown function is not used. |
| 4 | ADJ | input | Output-voltage adjust / feedback input. Set V_OUT with an R1/R2 divider from V_OUT to ADJ to GND: V_OUT = V_REF × (R1/R2 + 1), V_REF = 1.20 V typ. Divider resistors 470 kΩ-3 MΩ recommended to minimize bleeder current. A 100 pF-0.01 µF capacitor may be added to ADJ to reduce output noise. Input leakage typ 50 pA. |
| 5 | VOUT | power_out | Regulated voltage output. Adjustable from V_REF (1.20 V) up to V_IN − 0.05 V (max 5.5 V). Requires a 1 µF (min) capacitor to GND with ESR 0.1 Ω-5.0 Ω and self-resonance above 1 MHz for stability. Max output current 100 mA (TC1071); short-circuit current ~300 mA typ. |
