L78M12ABV datasheet by STMicroelectronics

L78M12ABV Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L78M12ABV?
  The maximum input voltage that can be applied to the L78M12ABV is 35V, although it's recommended to keep it below 25V for optimal performance and reliability.
• How do I ensure the L78M12ABV is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 2.2uF with an ESR (Equivalent Series Resistance) of less than 5 ohms, and keep the input capacitance as close to the regulator as possible.
• What is the minimum load current required for the L78M12ABV to operate properly?
  The L78M12ABV can operate with a minimum load current of 5mA, but it's recommended to have a minimum load of 10mA to ensure proper regulation and stability.
• Can I use the L78M12ABV in a high-temperature environment?
  The L78M12ABV is rated for operation up to 150°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the input voltage and output current at high temperatures to ensure reliable operation.
• How do I protect the L78M12ABV from input voltage surges and spikes?
  Use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the input capacitor to protect the L78M12ABV from input voltage surges and spikes.
