Instructions for LMR14050SDDA

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 3.0V to 60V.
   • Connect the input voltage source to the VIN pin.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted between 0.8V and 55V.
   • Use an external resistor network to set the desired output voltage according to the datasheet formula.

3. Output Current (IOUT):

   • The device can provide up to a continuous current of 500mA.
   • Ensure the load does not exceed this limit to avoid overheating or damage.

4. Quiescent Current (IQ):

   • At nominal operating conditions (VIN = 12V, VOUT = 5V), the quiescent current is approximately 70μA.
   • This low quiescent current ensures efficient operation at light loads.

5. Dropout Voltage (VDROPOUT):

   • The dropout voltage is around 400mV when delivering 500mA at VIN = 5V.
   • Keep this in mind when designing the power supply to ensure stable operation.

6. Power Dissipation (PD):

   • The maximum power dissipation at an ambient temperature of 25°C is 1.6W.
   • Proper heat sinking may be required for higher power applications.

7. Junction Temperature (TJ):

   • The operating junction temperature range is from -40°C to 125°C.
   • Ensure adequate thermal management to keep the junction temperature within these limits.
