PRODUCTION DATA
For the legacy chip, tantalum capacitors are the best choice for use at the output of the LDO. Most good-quality tantalums can be used with the LP2981-N (legacy chip), but check the manufacturer data sheet to be sure the ESR is in range. At lower temperatures, as ESR increases, a capacitor with ESR near the upper limit for stability at room temperature can cause instability. For very low temperature applications, output tantalum capacitors can be used in parallel configuration to prevent the ESR from going up too high.
