TPS75533KTTR

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

TPS75533KTTR 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 device down and a logic low enables it, with shutdown reducing quiescent current to less than 1 µA at TJ = 25°C.
2 IN power_in Input voltage to the regulator, specified at 2.8 V minimum to 5.5 V maximum in the recommended operating conditions.
3 GND power_in Regulator ground; the datasheet states the tab is also GND.
4 OUTPUT power_out Regulated output voltage, with output current rated 0 to 5 A and an output capacitor of at least 47 µF with ESR of at least 200 mΩ required between OUT and GND for stability.
5 FB/PG output For the fixed-output TPS75533 this is an open-drain, active-low power-good output that goes low when VO reaches about 91% of the regulated voltage and goes high-impedance below about 89%, requiring a pullup resistor; maximum PG voltage is 6 V.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
