SNVSA34E September 2014 – December 2019 LP5907-Q1
The LP5907-Q1 is designed specifically to work with a very small ceramic output capacitor, typically 1 µF. A ceramic capacitor (dielectric types X5R or X7R) in the 1-µF to 10-µF range, and with equivalent series resistance (ESR) between 5 mΩ to 500 mΩ, is suitable in the LP5907-Q1 application circuit. For this device connect the output capacitor between the OUT pin and a good connection back to the GND pin.
It may also be possible to use tantalum or film capacitors at the device output, VOUT, but these are not as attractive for reasons of size and cost (see Capacitor Characteristics).
The output capacitor must meet the requirement for the minimum value of capacitance and have an ESR value that is within the range 5 mΩ to 500 mΩ for stability. Like the input capacitor, the initial tolerance, applied voltage de-rating, and temperature coefficient must all be considered when selecting the input capacitor to ensure the actual capacitance is never less than 0.7 µF over the entire operating range.
