LM4120AIM5-1.8/NOPB datasheet by Texas Instruments

LM4120AIM5-1.8/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM4120AIM5-1.8/NOPB can handle?
  The maximum input voltage is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
• How do I ensure the stability of the output voltage?
  To ensure stability, use a minimum output capacitance of 10uF with an ESR of 0.1-10 ohms, and place the capacitor close to the output pin.
• What is the dropout voltage of the LM4120AIM5-1.8/NOPB?
  The dropout voltage is typically around 1.5V, but it can be as low as 1.2V under certain conditions. This means the input voltage should be at least 1.8V + 1.5V = 3.3V for proper operation.
• Can I use the LM4120AIM5-1.8/NOPB in a high-temperature environment?
  The device 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 or thermal pad to dissipate heat if necessary.
• How do I calculate the power dissipation of the LM4120AIM5-1.8/NOPB?
  Power dissipation (PD) can be calculated using the formula: PD = (VIN - VOUT) x IOUT. Make sure to keep the PD below the maximum rating of 1.4W to prevent overheating.
