LM293PT datasheet by STMicroelectronics

LM293PT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM293PT?
  The maximum input voltage that can be applied to the LM293PT is 26V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the output voltage is stable and regulated?
  To ensure a stable and regulated output voltage, make sure to use a suitable input capacitor (e.g., 10uF) and output capacitor (e.g., 22uF) as recommended in the datasheet, and keep the input voltage within the specified range.
• What is the minimum input voltage required for the LM293PT to operate?
  The minimum input voltage required for the LM293PT to operate is 7.5V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the LM293PT in a high-temperature environment?
  The LM293PT is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
• How do I protect the LM293PT from input voltage surges or spikes?
  To protect the LM293PT from input voltage surges or spikes, use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input, and ensure the input capacitor is rated for the maximum input voltage.
