TPS75901KTTR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-5

TPS75901KTTR from Texas Instruments, in a TO-263-5. 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 EN input Enable input: a logic high shuts the regulator down and a logic low enables it, with an absolute maximum voltage range of -0.3 V to 6 V.
2 IN power_in Input voltage to the regulator, with a recommended range of 2.8 V to 5.5 V and an absolute maximum range of -0.3 V to 6 V.
3 GND power_in Regulator ground.
4 OUTPUT power_out Regulated output voltage, with an adjustable-version output range of 1.22 V to 5 V and an absolute maximum of 5.5 V.
5 FB/PG bidirectional On the adjustable TPS75901 this is the feedback input, which must connect to OUTPUT (directly for 1.22 V minimum output or through a resistor divider), while on fixed options it is an open-drain active-low power-good output that requires a pullup resistor and has a maximum voltage of 6 V.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
