TPS70918QDBVRQ1

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

TPS70918QDBVRQ1 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 Unregulated input voltage with operating range 2.7V to 30V.
2 GND power_in Ground reference and thermal pad connection point for heat dissipation.
3 EN input Enable input; supply >0.9V to enable device, <0.4V to disable with 150nA shutdown current, or leave floating to enable; maximum voltage 6.5V.
4 NC unconnected No internal connection.
5 OUT power_out Regulated output voltage (1.2V to 6.5V depending on device variant); connect 2.2µF or larger ceramic capacitor to ground for stability.
