 The voltage at OUT must not be allowed to exceed the V
REG
 voltage, which is always 2.4 V less than the supply. For example, when the supply voltage is 5 V and the
output current is 1 mA, the load resistor must not be more than (5 V  2.4 V)/{1 mA ?(1 + 20%)}, or 2.17 k&, to ensure the signal does not exceed 2.6 V. As the supply
increases, the output signal also can be increased, by the same amount.
