Instructions for Use:
Input Voltage (VIN):
- Ensure the input voltage is within the range of 2.7V to 5.5V to avoid damage to the device.
Output Voltage (VOUT):
- The output voltage can be adjusted to 3.0V, 3.3V, or 3.6V depending on the specific variant of the LD3985M30R used. Verify the part number to ensure the correct output voltage.
Output Current (IOUT):
- The maximum continuous output current is 2.0A, with a typical value of 1.5A. Ensure the load does not exceed these limits to prevent overheating or damage.
Quiescent Current (IQ):
- The quiescent current is typically 2.0μA, which is very low, making the device suitable for battery-powered applications.
Dropout Voltage (VDROPOUT):
- The dropout voltage is typically 300mV. This means the input voltage must be at least 300mV higher than the output voltage to maintain regulation.
Shutdown Current (ISD):
- When the device is in shutdown mode, the current consumption is typically 0.1μA, which helps to conserve power in low-power applications.
Operating Temperature (TOP):
- The device can operate over a temperature range from -40°C to 125°C. Ensure the ambient temperature is within this range to maintain reliable operation.
Storage Temperature (TSTG):
- Store the device in an environment where the temperature ranges from -65°C to 150°C to prevent damage during storage.
Thermal Resistance (θJA):
- The thermal resistance from junction to ambient (θJA) is typically 50°C/W. Ensure proper heat dissipation to keep the junction temperature within safe limits.
Mounting and Handling:
- Handle the device with care to avoid mechanical stress. Follow standard ESD (Electrostatic Discharge) precautions to prevent damage.
Circuit Design:
- Use appropriate input and output capacitors to stabilize the regulator and filter out noise. Refer to the datasheet for recommended capacitor values and types.
PCB Layout:
- Place the input and output capacitors as close as possible to the regulator to minimize inductance and improve stability. Ensure adequate copper area for heat dissipation if high current operation is expected.
