TPS78228QDRVRQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-6-EP(2x2)

TPS78228QDRVRQ1 from Texas Instruments, in a WSON-6-EP(2x2). 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 OUT power_out Regulated output voltage pin; a small (1 μF) ceramic capacitor is needed from this pin to ground to assure stability.
2 NC unconnected Not connected.
3 GND power_in Ground pin; all ground pins must be tied to ground for proper operation.
4 EN input Enable pin: driving it above 1.2 V turns the regulator on and driving it below 0.4 V puts the regulator into shutdown, reducing operating current to 18 nA typical; absolute maximum is VIN + 0.3 V.
5 GND power_in Ground pin; all ground pins must be tied to ground for proper operation.
6 IN power_in Input pin with a small capacitor from this pin to ground for stability (typical 1.0 μF); input voltage range is 2.2 V to 5.5 V with an absolute maximum of 6.0 V.
7 Thermal Pad passive Exposed thermal pad on the SON-6 package; it is recommended that the thermal pad be connected to ground.
