# MCP1793T-5002H

**Microchip Tech** · Power Management - Specialized · SOT-23-5

MCP1793T-5002H 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 | Input Voltage Supply. Operating range 4.5V to 55V (up to 70V transient). Recommend 2.2 µF to 10 µF X7R ceramic input capacitor, especially with long leads or battery source. For a 5.0V output, minimum VIN is 6.2V to stay out of dropout. |
| 2 | GND | power_in | Ground reference. GND conducts only ground current (~100 µA typ at full load), so a wide trace is not required, but tie to a quiet circuit ground for best noise and PSRR performance. Also serves as the return for the output capacitor. |
| 3 | SHDN | input | Active-low Shutdown Control Input. Logic high (VIH ≥ 2.4V) enables the LDO output; logic low (VIL ≤ 0.8V, connect to GND) disables the output and drops the device to a ~2 µA low-quiescent shutdown state. Do not leave floating. Absolute max on SHDN is (GND - 0.3V) to (VIN + 0.3V). |
| 4 | NC | unconnected | No internal connection. Should either be left floating or tied to GND per the datasheet pin function table. |
| 5 | VOUT | power_out | Regulated Output Voltage VR. Fixed 5.0V nominal (VR ±2% for -40°C to +85°C, ±3% for -40°C to +150°C), 100 mA maximum continuous output. Requires a minimum 2.2 µF ceramic (X7R/X8R) output capacitor for stability; 3.3 µF X7R/X8R recommended over the full temperature range. Absolute max on VOUT is (GND - 0.3V) to 5.5V. |
