Hi, everyone :
Would anyone teach me what's the functions of the capicators in the ficture ?
The up part , which is part of a LDO :
T1 and T2 are all comomon collector connected , so they are voltage followers
and their output is the drive signal of the pass device of a LDO .
The down part ,which is part of another LDO :
T3 and T4 are common emitter connected , and their output is the drive signal
of the pass device of a LDO .
Are the capicators is used to increase the slew rate
of the drive signal ?
