LM293ADT datasheet by STMicroelectronics

LM293ADT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM293ADT can handle?
  The LM293ADT can handle input voltages up to 26V, but it's recommended to keep it below 24V for reliable operation.
• How do I ensure the output voltage is stable and accurate?
  To ensure a stable and accurate output voltage, make sure to use a suitable output capacitor (e.g., 10uF) and a minimum load current of 5mA. Also, keep the input voltage ripple below 1V.
• Can I use the LM293ADT in a high-temperature environment?
  The LM293ADT is rated for operation up to 125°C, but its performance may degrade above 85°C. Ensure proper heat sinking and thermal management to maintain reliability.
• How do I protect the LM293ADT from input voltage surges?
  Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit to protect the LM293ADT from input voltage surges and spikes.
• Can I use the LM293ADT in a low-dropout application?
  The LM293ADT has a relatively high dropout voltage (around 2V), so it's not suitable for low-dropout applications. Consider using a low-dropout regulator like the LDO series from STMicroelectronics instead.
