C1 is a low ESR ceramic capacitor used to minimize noise at the regulator. A tantalum or low ESR electrolytic capacitor may also be used. 2. C1 & C2 are required and should be mounted as close to the regulator pins as possible. Units MHours Component Values Model Number MicroPower Direct Max.

Load regulation is specified for an output load change of 10% to 100%. 2. Measured at an internal IC junction. 3. Quiescent current is specified at 0% load for Vin = min to max. 4. The output current limit on models with outputs between 1.5V and 3.3V is 3A. 5. This regulator is not designed to be used in parallel with another unit to increase output power. 6. The input should not exceed the range given in the model selection chart. Exceeding this limit could damage the unit.
