TPS74012DGKT

Texas Instruments · Linear Voltage Regulators (LDO) · VSSOP-8

TPS74012DGKT from Texas Instruments, in a VSSOP-8. 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 EN input Enable pin on the fixed output voltage version: driving it high enables the regulator, driving it low puts the regulator into shutdown, and it must not be left unconnected.
2 BIAS power_in Bias input voltage for the error amplifier, reference, and internal control circuits (VBIAS 2.9 V to 6.0 V per Features).
3 IN power_in Input to the device (VIN 1.2 V to 6.0 V per Features).
4 OUT power_out Regulated output voltage; a total typical capacitance of at least 2.2 µF (ceramic) to ground is needed for stability.
5 GND power_in Ground.
6 GND power_in Ground.
7 GND power_in Ground.
8 GND power_in Ground.
