Figure 24. High Output Current Linear Regulator
Higher Output Current
The ADP3303A can source up to 200 mA without any heatsink
or pass transistor. If higher current is needed, an appropriate
pass transistor can be used, as in Figure 24, to increase the
output current to 1 A.
Constant Dropout Post Regulator
The circuit in Figure 25 provides high precision with low drop-
out for any regulated output voltage. It significantly reduces the
ripple from a switching regulator while providing a constant
dropout voltage, which limits the power dissipation of the LDO
to 60 mW. The ADP3000 used in this circuit is a switching
regulator in the step-up configuration.
