# TPS79601DRBT

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SON-8-EP(3x3)

TPS79601DRBT from Texas Instruments, in a SON-8-EP(3x3). 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 | IN | power_in | Device input supply; 2.7 V to 5.5 V (old die) or 6.0 V (new die) recommended, with a 2.2 µF or larger ceramic capacitor to GND close to the device. |
| 2 | IN | power_in | Device input supply, internally common with pin 1; 2.7 V to 5.5 V (old die) or 6.0 V (new die) recommended. |
| 3 | OUT | power_out | Regulator output; requires an output capacitor to GND, 1 µF minimum recommended, for loop stability. |
| 4 | OUT | power_out | Regulator output, internally common with pin 3; requires an output capacitor to GND, 1 µF minimum recommended. |
| 5 | FB | input | Feedback input of the adjustable TPS79601, connected to an external resistor divider from OUT with a 1.225 V typical reference; an optional feed-forward capacitor can be placed from OUT to FB. |
| 6 | GND | power_in | Regulator ground. |
| 7 | N/C | unconnected | No internal connection; must be left open or connected to GND. |
| 8 | EN | input | Enable input; driving it high turns the regulator on, driving it low puts it in shutdown, and it can be tied to IN if unused. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
