【简　介】:
The reduced input voltage requirement
of an LDO is advantageous in batterypowered
systems, since it translates directly
into fewer battery cells, less wasted
power, smaller size, and lower cost.
The LDO’s higher level of performance
requires the use of external compensation
capacitors, something an NPN regulator
does not need. Also, the capacitors
must be carefully selected for
electrical parameters to assure stability.
This article will develop an overview of
LDO/NPN regulator theory, focusing on
loop compensation and the parameters
affecting regulator stability.
