LM193AYDT Frequently Asked Questions (FAQs)

  • STMicroelectronics recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • To ensure stability, a minimum output capacitance of 10uF with an ESR of less than 5 ohms is recommended. Additionally, the input capacitor should be at least 1uF with an ESR of less than 10 ohms.
  • The maximum allowed voltage drop across the regulator is 2V, but it's recommended to keep it below 1.5V to ensure optimal performance and minimize power dissipation.
  • The LM193AYDT is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Derating is required for operation above 85°C.
  • A TVS (Transient Voltage Suppressor) diode or a varistor can be used to protect the regulator from input voltage surges and spikes. A fuse can also be added to protect against overcurrent conditions.
