# TPS76038DBVR

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

TPS76038DBVR 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 | Input voltage pin; for the TPS76038 the recommended input is 4 V to 16 V, and the absolute input voltage range is -0.3 V to 16 V with respect to GND. |
| 2 | GND | power_in | Ground reference pin; all voltages are referenced to this device GND pin. |
| 3 | EN | input | Enable input; a logic low (0.8 V maximum) shuts the regulator off and reduces supply current to less than 1 µA, a logic high (2 V minimum) enables normal operation, and the pin must not be left floating. |
| 4 | NC | unconnected | No internal connection. |
| 5 | OUT | power_out | Regulated 3.8 V output for the TPS76038 at up to 50 mA; an output capacitor of at least 2.2 µF with ESR between 0.1 Ω and 20 Ω is required between OUT and GND for stability. |
