TPS78833DBVR 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 an input voltage range of 2.7 V to 10 V in the electrical characteristics and an absolute maximum of 13.5 V. |
| 2 | GND | power_in | Regulator ground pin for the device. |
| 3 | EN | input | Active-low enable input with a high-level threshold of 1.7 V minimum and a low-level threshold of 0.9 V maximum for 2.7 V < VI < 10 V, where EN = 0 V puts the regulator in standby with 2 µA maximum current. |
| 4 | SR | input | The SR terminal controls the in-rush current by setting the output voltage slew rate through an external slew-rate capacitor C(SR), such as 0.01 µF or 0.47 µF as used in the characteristic curves. |
| 5 | OUT | power_out | The OUT terminal is the regulated output of the device, providing 2.5 V (TPS78825) or 3.3 V (TPS78833) at a continuous output current of 0 to 150 mA. |
