Instructions for Use:

1. Mounting:

   • Ensure that the LM385BZ1.2 is mounted on a PCB with proper thermal management if high power dissipation is expected.
   • Use a heat sink if necessary to maintain the junction temperature within the specified limits.

2. Biasing:

   • The LM385BZ1.2 requires a minimum operating current of 1.0 mA for stable operation. Ensure that the biasing circuit provides this current.

3. Output Voltage:

   • The output voltage is typically 1.24 V under continuous operation with a load current of 1.0 mA.
   • The output impedance is very low (0.2 to 0.4 Ω), making it suitable for precision voltage reference applications.

4. Regulation:

   • The line regulation and load regulation are both very low (0.01%), ensuring minimal changes in output voltage with variations in input voltage or load current.

5. Temperature Sensitivity:

   • The temperature coefficient is ±10 ppm/°C, which means the output voltage will change by ±10 μV for every degree Celsius change in temperature.

6. Storage:

   • Store the device in a dry environment within the temperature range of -65°C to +150°C to ensure long-term reliability.

7. Handling:

   • Handle the device with care to avoid mechanical stress, which can affect its performance.
   • Follow ESD (Electrostatic Discharge) precautions to prevent damage to the device.

8. Testing:

   • When testing the device, ensure that all connections are secure and that the test setup is within the specified operating conditions.

9. Applications:

   • The LM385BZ1.2 is ideal for use in precision voltage reference circuits, power supplies, and other applications requiring a stable and accurate voltage source.
