LM34926MR/NOPB datasheet by Texas Instruments

LM34926MR/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM34926MR/NOPB?
  The maximum input voltage that can be applied to the LM34926MR/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage in the LM34926MR/NOPB?
  To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
• What is the maximum output current that the LM34926MR/NOPB can deliver?
  The maximum output current that the LM34926MR/NOPB can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation and to prevent overheating.
• How do I calculate the output voltage of the LM34926MR/NOPB?
  The output voltage of the LM34926MR/NOPB can be calculated using the formula: Vout = (R1/R2) * (Vin - Vref), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vref is the internal reference voltage (1.25V).
• What is the purpose of the EN pin on the LM34926MR/NOPB?
  The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled. This pin can be used to implement power sequencing or to turn off the regulator when not in use.
