# TPS76933QDBVRQ1

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

TPS76933QDBVRQ1 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 pin: use the recommended input capacitor from Recommended Operating Conditions (CIN 1 µF), placed as close as possible to the IN and GND pins; new-chip input range is 2.5 V to 16 V with an absolute maximum of 18 V. |
| 2 | GND | power_in | Ground reference pin; all device voltages are referenced to GND. |
| 3 | EN | input | Active-low enable: driving EN low enables the device and driving it high disables it, with the low and high thresholds given in the Electrical Characteristics table; new-chip EN voltage range is 0 V to 16 V and EN is internally pulled up, so it must not float. |
| 4 | FB/NC | unconnected | For the fixed-voltage version this pin is no connection on the old chip and must not be connected on the new chip; for the adjustable version (TPS76901-Q1) it is the feedback input and must not be left floating. |
| 5 | OUT | power_out | Regulated output pin: use the recommended output capacitor from Recommended Operating Conditions (new chip COUT at least 2.2 µF with ESR from 0 to 3 Ω), placed as close as possible to the OUT and GND pins; maximum output current 100 mA. |
