# TPS7A2430DBVR

**Texas Instruments** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPS7A2430DBVR from Texas Instruments, in a SOT-23-5. 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 | IN | power_in | Supply input pin accepting 2.4V to 18V with typical quiescent current of 2.0µA; place 1µF or larger capacitor close to IN and GND for best transient response and input impedance minimization. |
| 2 | GND | power_in | Ground reference pin (negative supply). |
| 3 | EN | input | Active-high enable pin; drive EN greater than 0.9V to enable regulator or less than 0.4V to shutdown; do not float this pin or connect to IN if unused. |
| 4 | NC | unconnected | No internal connection in fixed-voltage version; can float or tie to GND for improved thermal performance. |
| 5 | OUT | power_out | Regulated 3.0V output pin with ±1.25% accuracy and 200mA maximum output current; requires 1µF to 100µF output capacitor close to OUT and GND for stability. |
