TPS7A4525DCQR from Texas Instruments, in a SOT-223-6. 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 | SHDN | input | Pulling SHDN low puts the regulator into a low-power shutdown with the output off; it accepts 5-V, 3-V or open-collector logic with a high level of 2 V to 20 V, a low level of 0.25 V maximum, and must be connected to IN if unused. |
| 2 | IN | power_in | Power input with a recommended range of VOUT + VDO to 20 V and an absolute range of -20 V to 20 V, where a 1 µF to 10 µF ceramic bypass capacitor is recommended if the device is more than six inches from the main input filter capacitor. |
| 3 | GND | power_in | Ground reference for the regulator, and the datasheet's exposed-thermal-pad soldering requirement is stated for the KTT package rather than the DCQ package. |
| 4 | OUT | power_out | Regulated output that supplies the load and requires a minimum 10 µF ceramic output capacitor to prevent oscillations, with larger capacitors needed for large transient loads. |
| 5 | SENSE | input | Error-amplifier sense input for the fixed 2.5 V version, optimally connected to OUT or to the load to remove trace drop, with a bias current of 600 µA at the rated output voltage and allowed to be pulled below ground. |
| 6 | GND | power_in | Additional ground pin that is present on the DCQ package only. |
