# TPS78825DBVR

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

TPS78825DBVR 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 range of 2.7 V to 10 V and an absolute maximum of 13.5 V. |
| 2 | GND | power_in | Regulator ground pin, which is the return for the input and output of the regulator. |
| 3 | EN | input | Active-low enable input that turns the regulator on when pulled low; the high-level threshold is 1.7 V minimum and the low-level threshold is 0.9 V maximum for 2.7 V < VI < 10 V. |
| 4 | SR | input | The SR terminal is used to control the in-rush current by programming the output voltage slew rate through an external slew-rate capacitor C(SR). |
| 5 | OUT | power_out | The OUT terminal is the regulated output of the device, providing 2.5 V for this part with up to 150 mA continuous output current. |
