Instructions for Using the L6561D:

1. Supply Voltage (Vcc):

   • The L6561D operates with a supply voltage ranging from 10V to 35V. Ensure that the input voltage is within this range to avoid damage to the device.

2. Operating Temperature (Tj):

   • The junction temperature should be kept between -40°C and 150°C. Exceeding these limits can lead to device failure.

3. Storage Temperature (Tstg):

   • Store the device in an environment where the temperature ranges from -65°C to 150°C.

4. Maximum Output Current (Iout):

   • The maximum output current is 1.5A at 5V output and 25°C ambient temperature. Ensure that the load does not exceed this limit.

5. Quiescent Current (Iq):

   • The quiescent current is 5mA when the output voltage is 5V and there is no load. This is the current consumed by the device itself.

6. Dropout Voltage (Vdo):

   • The dropout voltage is 1.2V at 1.5A output current and 25°C ambient temperature. This is the minimum difference between the input and output voltages required for proper regulation.

7. Thermal Shutdown Temperature (TSD):

   • The device will shut down if the junction temperature exceeds 160°C. This is a safety feature to prevent overheating.

8. Hysteresis (Hys):

   • The hysteresis is 15mV, which helps in stabilizing the output voltage and preventing oscillations.

9. Enable Input High Level (Vin(H)):

   • The enable input should be at least 2.3V to turn the device on.

10. Enable Input Low Level (Vin(L)):

    • The enable input should be below 0.8V to turn the device off.

Additional Notes:

• Always use appropriate heat sinking if operating the device at high temperatures or high currents.
• Ensure that the input and output capacitors are rated for the expected operating conditions to maintain stability.
• Follow the recommended PCB layout guidelines to minimize noise and improve performance.
