Input Voltage (VIN):
- Ensure the input voltage is within the range of 2.7V to 5.5V for stable operation.
Output Voltage (VOUT):
- The device provides a fixed output voltage of 3.3V. No external components are required to set this voltage.
Output Current (IOUT):
- The device can supply up to 2.0A continuously. For currents exceeding 1.5A, ensure adequate heat sinking to prevent overheating.
Quiescent Current (IQ):
- At no load and with an input voltage of 5V, the quiescent current is approximately 60渭A.
Shutdown Mode:
- Apply a low signal to the SHDN pin to put the device into shutdown mode, reducing the current draw to about 1渭A.
Dropout Voltage:
- When delivering 500mA, the dropout voltage is typically between 400mV and 550mV. Ensure that the input voltage exceeds the output voltage by at least this amount.
Power Supply Rejection Ratio (PSRR):
- At 1kHz, the PSRR is around 60dB, indicating good noise rejection from the input supply.
Operating Temperature:
- The device can operate within a junction temperature range of -40掳C to 125掳C. Ensure proper thermal management for reliable operation in high-temperature environments.
