Good quality, low ESR tantalum or aluminum electrolytic capacitors should be used. Increasing the value of the output capacitor will improve the overall transient response. (2) If the same voltage is input to both POWER and CONTROL, then the dropout voltage will become 1.3V maxi- mum. (3) A small (~0.033µF) capacitor can be used to bypass the ADJUST pin to improve transient response, if needed. |
