Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
TPS79328QDBVRQ1 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 | Regulator input; recommended supply range is 2.7 V to 5.5 V, and a 0.1 µF or larger ceramic input capacitor is needed between IN and GND for stability. |
| 2 | GND | power_in | Regulator ground; the datasheet asks that the ground planes for VIN and VOUT be joined only at this pin to help AC performance. |
| 3 | EN | input | Active-high enable; the device turns on when EN is above VEN(HI) (0.85 × VIN on the new chip, 1.7 V on the old chip) and turns off below VEN(LOW) (0.425 V new chip, 0.7 V old chip), and EN should be tied to IN if shutdown is not needed. |
| 4 | BYPASS | passive | On the old chip this pin is BYPASS, connected through an internal 250 kΩ resistor to the voltage reference, where an external capacitor (0.01 µF typical in the test conditions) filters reference noise and must have minimal leakage; on the new chip this pin is NC, not internally connected, and may be tied to GND for thermal performance or left floating. |
| 5 | OUT | power_out | Regulated output at 2.8 V nominal (2.744 V to 2.856 V over 0 to 200 mA), requiring at least 2.2 µF of output capacitance on the old chip or at least 0.47 µF effective on the new chip. |
