# TPS72218DBVR

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

TPS72218DBVR 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 supply voltage; the recommended input range is 1.8 V to 5.5 V, and the absolute maximum input voltage is -0.3 V to 7 V. |
| 2 | GND | power_in | Ground terminal, which is the network ground reference for all voltages in the datasheet. |
| 3 | EN | input | Enable input; logic high (VIH) is 1.4 V minimum, logic low (VIL) is -0.2 V to 0.4 V, and the voltage range at EN is -0.3 V to 7 V, with a logic low shutting off the output. |
| 4 | NC/FB | unconnected | Not connected on the fixed-voltage TPS72218; this pin must be left floating and not connected to GND (FB feedback input applies only to the adjustable TPS72201). |
| 5 | OUT | power_out | Regulated output voltage; voltage on OUT is limited to -0.3 V to VI + 0.3 V per the absolute maximum ratings, and output current is 0 to 50 mA. |
