TLV71312PQDBVRQ1 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input supply pin. Operating range 1.4 V to 5.5 V (absolute max 6 V). A small (up to 1 µF) ceramic bypass capacitor to GND is recommended but not required due to the capacitor-free architecture. |
| 2 | GND | power_in | Ground reference pin for the regulator. Ground pin current I_GND is typically 50 µA (75 µA max). |
| 3 | EN | input | Enable input. Driving EN above 0.9 V (V_HI) turns on the regulator; driving below 0.4 V (V_LO) puts the device into shutdown mode (I_SHUTDOWN ≈ 0.1 µA typ). EN input current is negligible (≈0.01 µA at 5.5 V). Absolute max is V_IN + 0.3 V. |
| 4 | NC | unconnected | No internal connection. May be left floating or tied to GND. |
| 5 | OUT | power_out | Regulated output voltage pin (1.2 V nominal for this orderable). Delivers up to 150 mA with typical dropout of 230 mV. Capacitor-free stable; a 1 µF ceramic capacitor to GND is recommended for best transient response. Includes an active pulldown (~120 Ω typ) for fast discharge when disabled. |
