TPS78533QKVURQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-4

TPS78533QKVURQ1 from Texas Instruments, in a TO-252-4. 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; drive to logic high to enable device, logic low to disable device; do not float this pin, if not used connect EN to IN.
2 IN power_in Input pin for supply voltage 1.7V to 6.0V; place nominal recommended value or larger ceramic capacitor from IN to GND as close to device input as possible.
3 GND power_in Ground pin, must be connected to ground on board; thermal pad is electrically connected to GND and should be connected to large-area GND plane for improved thermal performance.
4 OUT power_out Output pin; 0.47µF or greater effective capacitance required from OUT to ground for stability; use 1µF or larger ceramic capacitor for best transient response; place as close to output as possible.
5 NC unconnected No connect pin, not internally connected; connect to ground for best thermal performance or leave floating.
