TLV74318PDBVR 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 | Unregulated supply input, 1.4 V to 5.5 V (absolute max 6 V). A small ceramic input capacitor from IN to GND is recommended for stability and transient response. |
| 2 | GND | power_in | Device ground reference. All other pin voltages are referenced to this node. |
| 3 | EN | input | Enable input. Drive EN greater than V_EN(HI) to turn on the regulator; drive EN less than V_EN(LO) to put the LDO into shutdown mode. Recommended EN range is 0 V to V_IN (abs max 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 (1.8 V fixed for the TLV74318P option). Sources up to 300 mA. For best transient response, use a small 1-µF ceramic capacitor from OUT to GND. Includes active pulldown discharge when the device is disabled. |
