# TPS73030DBVT

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

TPS73030DBVT 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 | Device input; recommended VIN range is 2.7 V to 5.5 V, and a ceramic bypass capacitor of at least 0.1 µF (old chip) or 1 µF (new chip) should be placed close to the device between IN and GND. |
| 2 | GND | power_in | Regulator ground. |
| 3 | EN | input | Enable pin, active high: driving EN above VEN(HI) (1.7 V min for the old chip) turns the regulator on and driving it below VEN(LOW) (0.7 V max for the old chip) puts it in shutdown; EN must not be left floating and may be tied to IN if shutdown is not needed. |
| 4 | NC/NR | passive | On the old chip this is the noise-reduction pin, where an external capacitor (0 to 10 nF recommended) filters bandgap noise and must not be loaded resistively or inductively; on the new chip it is not internally connected and may be tied to GND for better thermal performance or left floating. |
| 5 | OUT | power_out | Regulator output, specified at ±2% of VOUT(nom) for 0 to 200 mA load, requiring at least 2.2 µF ceramic COUT between OUT and GND (placed close to the device). |
