Instructions for UTC78D15L

1. Input Voltage (VI):

   • Ensure the input voltage is within the operating range of 17V to 30V. Exceeding this range can damage the device.

2. Output Voltage (VO):

   • The regulator maintains a stable output voltage of 15V. This value is fixed and does not require external components for setting.

3. Output Current (IO):

   • The maximum continuous output current is 1.5A. Avoid exceeding this limit to prevent overheating or damage.

4. Line Regulation:

   • The line regulation is very tight at 0.01%, ensuring minimal changes in output voltage due to variations in input voltage.

5. Load Regulation:

   • Load regulation is 0.1%, indicating stable output voltage under varying load conditions from no load to full load.

6. Dropout Voltage (VD):

   • At full load (1.5A), the dropout voltage is typically 2.5V. Ensure that the input voltage remains sufficiently higher than the output voltage by this margin.

7. Quiescent Current (IQ):

   • With no load, the quiescent current is approximately 5mA, contributing minimally to power consumption.

8. Ripple Rejection:

   • The regulator provides good ripple rejection of 60dB at 120Hz, effectively filtering out noise from the input supply.

9. Operating Temperature (Toper):

   • The device operates reliably between -40掳C and 85掳C. Ensure adequate heat dissipation if operating near the upper temperature limit.

10. Storage Temperature (Tstg):

    • The storage temperature range is from -65掳C to 150掳C, allowing for safe storage in a wide range of environments.

Ensure all connections are secure and properly insulated to avoid short circuits and ensure reliable operation.
