LM193H datasheet by Texas Instruments

LM193H Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM193H?
  The maximum input voltage that can be applied to the LM193H is 42V, but it's recommended to keep it below 35V for reliable operation.
• How do I ensure the LM193H is stable and doesn't oscillate?
  To ensure stability, use a minimum output capacitance of 10uF with an ESR of 5 ohms or less, and keep the input and output capacitors close to the regulator.
• Can I use the LM193H in a high-temperature environment?
  The LM193H is rated for operation up to 125°C, but the junction temperature should be kept below 150°C to ensure reliability. Use a heat sink if necessary.
• How do I calculate the power dissipation of the LM193H?
  Power dissipation (PD) = (Vin - Vout) x Iout. Ensure the PD is within the maximum rating of 1.5W for the LM193H.
• Can I use the LM193H as a negative voltage regulator?
  No, the LM193H is designed for positive voltage regulation only. For negative voltage regulation, consider using a different regulator like the LM79L series.
