LP2901D datasheet by Texas Instruments

LP2901D Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP2901D?
  The maximum input voltage that can be applied to the LP2901D is 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I ensure the LP2901D is stable and doesn't oscillate?
  To ensure stability, make sure to decouple the input and output with capacitors, use a minimum of 10uF capacitor at the output, and keep the layout clean and compact.
• What is the minimum load current required for the LP2901D to regulate properly?
  The LP2901D can regulate properly with a minimum load current of 5mA, but it's recommended to have a minimum load of 10mA for optimal performance.
• Can I use the LP2901D in a high-temperature environment?
  The LP2901D is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures.
• How do I protect the LP2901D from input voltage transients?
  Use a TVS diode or a transient voltage suppressor at the input to protect the LP2901D from voltage transients and spikes.
