_______________________________________________________________________________________

Note 1: If the load current exceeds 300µA, connect a minimum of 1000pF from VOUT to GND. Note that if a capacitor larger than

1000pF is used, a compensation capacitor of COUT/100 must be connected from VOUT to COMP.
