# TPS79530DCQR

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-6

TPS79530DCQR 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 | EN | input | Enable pin: driving it high turns the regulator on, driving it low puts the regulator in shutdown mode, and EN can be connected to IN if shutdown is not used. |
| 2 | IN | power_in | Input supply pin of the regulator. |
| 3 | GND | power_in | Regulator ground pin; pins 3 and 6 are both GND. |
| 4 | OUT | power_out | Regulator output pin. |
| 5 | NR/FB | passive | On the old-die fixed-voltage version (as in TPS79530), NR is a high-impedance noise-reduction pin where a low-leakage bypass capacitor of 0.1 µF or less is connected to GND; on the new die this pin is N/C, and FB is used only on adjustable versions. |
| 6 | GND | power_in | Regulator ground pin; pins 3 and 6 are both GND. |
