MAX628CPA+ datasheet by Maxim Integrated Products

MAX628CPA+ Frequently Asked Questions (FAQs)

• What is the recommended output capacitor value for the MAX628CPA+?
  The recommended output capacitor value is 10uF to 22uF, but it can be adjusted based on the specific application and noise requirements.
• How does the MAX628CPA+ behave during power-up and power-down?
  The MAX628CPA+ has a soft-start feature that prevents output voltage overshoot during power-up. During power-down, the output voltage decays rapidly to prevent latch-up.
• What is the maximum allowed input voltage for the MAX628CPA+?
  The maximum allowed input voltage is 12V, but it's recommended to keep it below 10V to ensure reliable operation and minimize power consumption.
• Can I use the MAX628CPA+ in a high-temperature environment?
  Yes, the MAX628CPA+ is rated for operation up to 125°C, but the output voltage accuracy and long-term stability may degrade at high temperatures.
• How does the MAX628CPA+ handle input voltage noise and ripple?
  The MAX628CPA+ has a high power supply rejection ratio (PSRR) of 90dB, which helps to reject input voltage noise and ripple, ensuring a stable output voltage.
