LM193DR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM193DR is 30V, but it's recommended to keep it below 25V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of 5 ohms or less, and keep the input and output capacitors close to the regulator.
  • The LM193DR is rated for operation up to 125°C, but its performance may degrade at high temperatures. Consider using a heat sink or reducing the input voltage to minimize thermal stress.
  • Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp at the input to protect the regulator from voltage spikes and transients.
  • The LM193DR 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 TLV703 or TPS799 instead.
