**Co is not needed for stability, however, it does improve transient response.
Vout = 1.25 V (1+R2/R1) + IAdjR2
Since IAdj is controlled to less than 100µA, the error associated with this term is
negligible in most applications.

Notes: 1. Imax=100mA, Pmax=625mW;
2. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating
effects must be taken into account separately. Pulse testing with low duty cycle is used.
