PRECISION BOOSTED OUTPUT REGULATOR
A precision voltage output with boosted current capability can
be realized with the circuit shown in Figure 43. In this circuit,

U2 forces V O to be equal to V REF by regulating the turn-on of
N1. Therefore, the load current is furnished by V IN . In this
configuration, a 50 mA load is achievable at a V IN of 5 V. Moderate
heat is generated on the MOSFET, and higher current can be
achieved with a replacement of the larger device. In addition,

for a heavy capacitive load with step input, a buffer can be
added at the output to enhance the transient response.
