# TPS71525DCKR

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

TPS71525DCKR 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 | NC | unconnected | No connect pin; not connected internally, connect to ground for thermal performance or leave floating. |
| 2 | GND | power_in | Ground pin; reference potential for regulator operation. |
| 3 | NC | unconnected | No connect pin; not connected internally, connect to ground for thermal performance or leave floating. |
| 4 | IN | power_in | Input supply pin; 2.5 V to 24 V input voltage range with 0.1 µF minimum input capacitor to ground recommended. |
| 5 | OUT | power_out | Regulated output pin at fixed 2.5 V nominal; requires 1 µF minimum output capacitor to ground for stability. |
