# TPS78925DBVR

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

TPS78925DBVR 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 | The IN terminal is the input to the device, with a recommended input voltage range of 2.7 V to 10 V and VI(min) equal to VO(max) plus the dropout voltage at maximum load. |
| 2 | GND | power_in | Regulator ground, which also carries the quiescent current; the output capacitor must connect between OUT and GND with a minimum of 4.7 µF. |
| 3 | EN | input | Active low enable: a voltage of 1.7 V or greater disables the device and a voltage below 0.9 V enables it. |
| 4 | BYPASS | input | The external bypass capacitor, in conjunction with an internal 150-kΩ resistor, creates a low-pass filter to further reduce regulator noise. |
| 5 | OUT | output | The OUT terminal is the regulated output of the device, rated up to 100 mA continuous output current. |
