TPS7A4501DCQR from Texas Instruments, in a SOT-223-6. 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 | SHDN | input | Shutdown control input; pull low to disable output, pull high for regulated operation; can be driven by 3 V, 5 V, or open-collector logic with pullup resistor; typical SHDN current 3 μA. |
| 2 | IN | power_in | Power supply input; accepts 1-20 V; requires 1-10 μF ceramic bypass capacitor; withstands ±20 V reverse voltage without reverse current flow into device. |
| 3 | GND | power_in | Ground reference. |
| 4 | OUT | power_out | Regulated output; requires minimum 10 μF ceramic output capacitor with ESR ≤3 Ω to prevent oscillations; supplies up to 1.5 A. |
| 5 | ADJ | input | Adjustable reference input for voltage programming; maintains 1.21 V referenced to ground; accepts external resistor divider for 1.21-20 V output range; internally clamped to ±7 V with 3 μA bias current flowing into pin. |
| 6 | GND | power_in | Ground reference; DCQ package only. |
