# TP9091-330T11U

**TECH PUBLIC** · Linear Voltage Regulators (LDO) · SOT-23-5

TP9091-330T11U from TECH PUBLIC, 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 | VIN | power_in | Supply power input; absolute maximum 6 V, recommended input 1.6V~5.5V with a 1uF input capacitor to ground. |
| 2 | GND | power_in | Ground. |
| 3 | CE | input | Enable pin; standby current is typically 1 uA when CE is at 0 V. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated voltage output (3.3 V for the -330 option), up to 300 mA typical, with a 1uF output capacitor to ground. |
