The diode D1 is used to protect the module against a reverse connection. 2. C1 is required if a high voltage input to the regulator is used. It will help prevent voltage spikes that could possibly damage the regulator. If used, the value should be 47 µF minimum 2. This circuit example shows a simple connection utilizing a second regulator to provide a second regulated output.

Load regulation is specified for an output load change of 10% to 100%. 2. Operation under 10% load will not damage the unit. However, it may not meet all specifications. 3. Measured at an internal IC junction. 4. Quiescent current is specified at 0% load for VIN = nom. 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.
