# TPS78930DBVR

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

TPS78930DBVR 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 | The IN terminal is the input to the device, with a recommended input voltage of 2.7 V to 10 V and an absolute maximum input voltage range of -0.3 V to 13.5 V. |
| 2 | GND | power_in | Regulator ground pin, which is the return for the input and output and is referenced by all voltage ratings in the datasheet. |
| 3 | EN | input | Active-low enable: a voltage of 1.7 V or greater disables the regulator and reduces supply current to 1 µA, while a voltage below 0.9 V enables it, with absolute limits of -0.3 V to VI. |
| 4 | BYPASS | passive | The external bypass capacitor connects to an internal 150 kΩ resistor to form a low-pass filter that reduces reference noise, and a larger bypass capacitance slows output start-up because of the RC time constant. |
| 5 | OUT | power_out | The OUT terminal is the regulated output, rated for 0 mA to 100 mA continuous output current with a voltage on OUT absolute maximum of 7 V. |
