TPS72118DBVR

Texas Instruments · Linear Voltage Regulators (LDO) · SOT-23-5

TPS72118DBVR 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 pin; the datasheet's VIN range is 1.8 V to 5.5 V and the input must be at least VOUT + VDO.
2 GND power_in Ground pin, the network ground reference for all voltages on the device.
3 EN input Enable input; a logic low (below 0.4 V VIL) shuts off the output and EN may be tied to IN when shutdown is not used.
4 NC/FB unconnected Not connected on the fixed-output TPS72118 and must be left floating and not connected to GND; it is the feedback input only on the adjustable TPS72101.
5 OUT power_out Regulated output voltage pin, rated for 150 mA continuous output current (IOUT 0 to 150 mA).
