# TPS73230MDBVREP

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

TPS73230MDBVREP from Texas Instruments, in a SOT-23-5. 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 | IN | power_in | Unregulated input supply to the regulator, with an input voltage range of 1.7 V to 5.5 V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Enable input: driving it high (VEN(HI) 1.7 V to VIN) turns the regulator on and driving it low (VEN(LO) 0 V to 0.5 V) puts it in shutdown; it may be connected to IN if unused. |
| 4 | NR | passive | For the fixed-voltage version only, an external capacitor connected to this pin bypasses the internal bandgap noise and lowers output noise. |
| 5 | OUT | power_out | Regulator output, which is stable without any external output capacitor. |
