# TPS79333DBVRG4Q1

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

TPS79333DBVRG4Q1 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 | input | Device input terminal with recommended input voltage range 2.7V to 5.5V |
| 2 | GND | power_in | Regulator ground terminal |
| 3 | EN | input | Enable input for device control; device enables when EN pin transitions to logic high, enters shutdown mode when EN is at logic low |
| 4 | BYPASS | passive | External bypass capacitor pin (old chip variant only) forming low-pass filter with internal 250kΩ resistor to attenuate voltage reference noise |
| 5 | OUT | output | Regulated output terminal providing 3.3V nominal output voltage (3.234V to 3.366V typical for 0µA to 200mA load current, 4.3V to 5.5V input), maximum 200mA continuous output current |
