TLV77033PDBVR 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 supply with a VIN range of 1.4 V to 5.5 V; use the nominal or larger input capacitor from IN to ground, placed as close to the IN and GND pins as possible. |
| 2 | GND | power_in | Common ground; all voltages are specified with respect to this pin. |
| 3 | EN | input | Enable input: a voltage below VEN(LOW) turns the regulator off and discharges OUT to GND, a voltage above VEN(HI) enables the output, and the pin is rated 0 V to 5.5 V. |
| 4 | N/C | unconnected | No internal electrical connection; connect to GND for improved thermal performance. |
| 5 | OUT | power_out | Regulated output voltage (0.6 V to 3.3 V nominal) requiring a low-ESR capacitor from OUT to ground (0.47 µF to 40 µF effective, ESR up to 100 mΩ), with an internal pulldown that discharges the output in shutdown. |
