TPS75933 is very low dropout 3.3V voltage regulator, which means it drop only small amount power in it. The main features are ·       Maximum current of 7.5A ·       Thermal Shutdown Protection ·       Maximum input voltage 6V Pin description 1.      EN – if ground is given this it will work.if we applied Vcc to this pin output will be 0V. 2.      IN – unregulated input voltage (Maximum input voltage 6V) 3.      GND 4.      OUTPUT 5.      PG-Power-Good –This pin indicates overload condition. It is open drain output. So it needs a pull-up resistor to get the indication. Output will low when output voltage is above 91% 3.3V. If output voltage is below 91% output will high. No need to include circuit.  Application Circuit 1)As a fixed voltage regulator Capacitors are used for to avoid ripples in input and output side. 2)As a high current switch EN – Enable can be used to turn on and turn off the load.The logic high wills shutdown the regulator and vice-versa. Use pull-up resistor to avoid unwanted floating values.
