Instructions for Using ML4824
Input Voltage (VIN):
- Ensure the input voltage is within the specified range of 3.0V to 5.5V.
- Use appropriate decoupling capacitors (e.g., 10μF) close to the input pin to filter out noise.
Output Voltage (VOUT):
- The ML4824 provides a fixed output voltage of 3.3V. If a different output voltage is required, use external resistors to adjust it.
- Connect a bypass capacitor (e.g., 10μF) to the output pin to stabilize the output and reduce ripple.
Quiescent Current (IQ):
- The quiescent current is typically 10μA and can go up to 20μA. This is the current drawn by the regulator when there is no load.
Dropout Voltage (VDROP):
- The dropout voltage is the minimum difference between the input and output voltages required to maintain regulation. It is typically 120mV and can go up to 200mV at maximum load.
Load Regulation:
- The load regulation is the change in output voltage as the load current changes. It is typically 0.5% and can go up to 2.0%.
Line Regulation:
- The line regulation is the change in output voltage as the input voltage changes. It is typically 0.1% and can go up to 0.5%.
Transient Response:
- The transient response is the output voltage deviation during load transients. Ensure that the output capacitors are sufficient to handle these transients.
Thermal Shutdown (TSHDN):
- The device will shut down if the temperature exceeds 160°C to prevent damage. Ensure proper heat dissipation and avoid operating in environments where the temperature can exceed this limit.
Short-Circuit Current (ISC):
- The maximum short-circuit current is 200mA to 300mA. The device has built-in protection to limit the current and prevent damage.
Operating Temperature (TA):
- The operating temperature range is from -40°C to 85°C. Ensure that the device is used within this range to avoid performance degradation or failure.
Additional Notes:
- Always refer to the datasheet for the most accurate and detailed information.
- For optimal performance, follow the recommended PCB layout guidelines provided in the datasheet.
