TPS78918DBVR

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

TPS78918DBVR 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 to the regulator; operating voltage range 2.8 V to 10 V for TPS78918
2 GND power_in Regulator ground reference potential
3 EN input Active-low enable input; device enabled at voltages less than 0.9 V, disabled at voltages 1.7 V or greater, switching threshold approximately 1.5 V
4 BYPASS passive External bypass capacitor connection forming low-pass filter with internal 150-kΩ resistor to reduce regulator output noise
5 OUT power_out Regulated output voltage of 1.8 V nominal for TPS78918, with maximum continuous output current of 100 mA and internal current limit at approximately 350 mA
