Instructions:

1. Input Voltage (V_IN): Ensure the input voltage is within the range of 2.5V to 5.5V for optimal performance.
2. Output Voltage (V_OUT): The output voltage is fixed at 3.3V. No external resistors are required for setting this voltage.
3. Output Current (I_OUT): The device can provide a continuous output current up to 2.0A, with typical performance at 1.5A.
4. Quiescent Current (I_Q): Operates with a quiescent current of 45μA when the output voltage is set to 3.3V.
5. Shutdown Current (I_SD): When in shutdown mode and VIN is 5V, the current consumption drops to 0.1μA.
6. Dropout Voltage (V_DROPOUT): At an output current of 200mA, the dropout voltage is typically 200mV.
7. Power Supply Rejection Ratio (PSRR): Provides a rejection ratio of 70dB at 1kHz, ensuring minimal noise from the power supply reaches the output.
