# TPS76333DBVT

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

TPS76333DBVT 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 | Input supply pin for 2.7V to 10V; use 1µF or larger capacitor from this pin to ground. |
| 2 | GND | power_in | Ground reference. |
| 3 | EN | input | Enable pin for LDO; drive high to enable device, low to disable; tie to VIN if unused (for new chip). |
| 4 | NC | unconnected | No connection (fixed-voltage option only). |
| 5 | OUT | power_out | 3.3V regulated output; use 2.2µF or larger capacitor from this pin to ground. |
