MCP1801T-3302I from TECH PUBLIC, 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, 2.0 V to 10 V operating range (12 V absolute max). Bypass to GND with a 1 µF capacitor close to the pin. |
| 2 | VSS | power_in | Ground / common return terminal for the regulator (labeled VSS in the pinout and GND in the pin-function table and block diagram). |
| 3 | SHDN | input | Active-low shutdown input. Logic high (VIH ≥ 1.6 V, up to VIN) enables the regulator; logic low (VIL ≤ 0.25 V) disables the output and drops standby current to ~0.01 µA typical. |
| 4 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net; not electrically bonded to the die. |
| 5 | VOUT | power_out | Regulated 3.3 V output, up to 150 mA continuous (typical dropout 200 mV @ 100 mA, 60 mV @ 30 mA). Requires a minimum 1 µF output capacitor for stability; low-ESR ceramic/tantalum/aluminum electrolytic acceptable. |
