Instructions for Use:
Input Voltage (VIN):
- Ensure the input voltage is within the range of 3.0V to 60V.
- The input voltage should be stable and free from excessive noise.
Output Voltage (VOUT):
- The output voltage can be adjusted up to 50V.
- Use an external resistor network to set the desired output voltage according to the datasheet formula.
Output Current (IOUT):
- The device can provide a continuous output current of up to 2A.
- For higher current applications, ensure proper heat dissipation and thermal management.
Quiescent Current (IQ):
- The quiescent current is typically 70μA when there is no load and the input voltage is 12V.
- This low quiescent current helps in reducing power consumption in low-power systems.
Dropout Voltage (VDROPOUT):
- The dropout voltage is typically 1.2V at an output current of 1A.
- Ensure that the input voltage is at least 1.2V higher than the output voltage to maintain regulation.
Load Regulation:
- The load regulation is 0.1% over the output current range from 0mA to 2A.
- This ensures minimal changes in output voltage with varying load conditions.
Line Regulation:
- The line regulation is 0.01%/V over the input voltage range from 3V to 60V.
- This ensures minimal changes in output voltage with varying input voltage.
PSRR (Power Supply Rejection Ratio):
- The PSRR is 70dB at 1kHz, which helps in rejecting input voltage variations and noise.
- This is particularly important in noisy environments or where the input voltage may fluctuate.
Operating Temperature (TJ):
- The device can operate at junction temperatures ranging from -40°C to 125°C.
- Ensure proper heat sinking if operating at high temperatures or high output currents.
Storage Temperature (TSTG):
- The device can be stored at temperatures ranging from -65°C to 150°C.
- Store the device in a dry, cool place to avoid damage.
Additional Notes:
- Always refer to the specific application notes and datasheet for detailed information and recommended circuit designs.
- Ensure all components used in the circuit are rated appropriately for the operating conditions.
- Proper PCB layout and component selection are crucial for optimal performance and reliability.
