L295 datasheet by STMicroelectronics

L295 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the L295?
  The maximum input voltage that can be applied to the L295 is 35V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the L295 is stable and doesn't oscillate?
  To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) should be between 0.5Ω and 10Ω. Additionally, a 10nF capacitor between the input and ground can help reduce noise and oscillations.
• What is the minimum input voltage required for the L295 to regulate properly?
  The minimum input voltage required for the L295 to regulate properly is 7.5V for the 5V output version, and 10.5V for the 12V output version.
• Can I use the L295 in a high-temperature environment?
  The L295 is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. It's recommended to derate the output current at high temperatures to prevent overheating.
• How do I protect the L295 from input voltage surges and spikes?
  A TVS (Transient Voltage Suppressor) diode or a varistor can be used to protect the L295 from input voltage surges and spikes. A 1kΩ resistor in series with the input can also help to reduce the voltage spike energy.
