摘要：
A micropower low-dropout regulator (LDO) (30) having a low dropout voltage and a method of compensating base current errors. The new compensation technique involves placing a shunt capacitor (C 2 ) at a counterphase input (node A) of a Brokaw transconductance cell incorporating a base current compensation resistor (R 5 ).
