C1 & C2 are low ESR ceramic capacitors 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. C3 is required for optimum performance, use 100 µF OR more. 3. R1 & R2 are used to adjust the regulator output.

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. This regulator is not designed to be used in parallel with another unit to increase output power. 5. The remote on/off control current is typically 2 µA. Shutdown Min Max input current is 30 µA max. The On/Off shutdown threshold Open or 1.5V
