# TPS7A2501DRVR

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-6-EP(2x2)

TPS7A2501DRVR from Texas Instruments, in a WSON-6-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Regulated output voltage; requires output capacitor (2.2μF nominal, 1 to 100μF range) to ground for stability and transient response; place capacitor close to OUT and GND pins. |
| 2 | FB | input | Feedback input to control-loop error amplifier; sets regulated output voltage using external resistor divider in adjustable-version devices only. |
| 3 | PG | tri_state | Open-drain power-good output; driven low when VOUT below 84% to 90% of nominal, pulled high by external resistor when VOUT above 93% to 96.5% of nominal. |
| 4 | EN | input | Active-high enable control input; drive above 0.9V to enable regulator, below 0.4V to enter low-current shutdown; do not float this pin. |
| 5 | GND | power_in | Ground reference return pin for all internal circuits and external capacitors. |
| 6 | IN | power_in | Input supply voltage pin accepting 2.4V to 18V; input capacitor (minimum 1μF) to ground recommended for transient response; place capacitor close to IN and GND pins. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
