# TPS71501QDCKRQ1

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5

TPS71501QDCKRQ1 from Texas Instruments, in a SC-70-5. 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 | FB | input | Feedback input pin; sets the output voltage with external feedback divider network in adjustable configuration. |
| 2 | GND | power_in | Ground pin; ground reference for the device. |
| 3 | NC | unconnected | No connect pin not connected internally; connect to ground for best thermal performance or leave floating. |
| 4 | IN | power_in | Input supply pin; accepts supply voltage from 2.5 V to 24 V; requires optional 0.047 µF input capacitor to minimize source impedance effects. |
| 5 | OUT | power_out | Output of the regulator; adjustable from 1.2 V to 15 V; requires minimum 0.47 µF output capacitor for stability. |
