Moreover, such values for any two items must not be reached simultaneously. Operation above   these absolute maximum ratings may cause degradation or permanent damage to the device. These are stress   ratings only and do not necessarily imply functional operation below these limits.   4 Download from Www.Somanuals.com.

Output Current IOUT is   obtained as follows :   IOUT   VIN   VOUT   R×5RL   VIN   SERIES   R 1 * IOUT= Vreg /R + ISS   GND   + ISS   C1   Take care that Output Current IOUT does not exceed   its allowable current.   1) Vreg : Set Output Voltage of R×5RL Series.   * 17   Download from Www.Somanuals.com.
