Current Regulator
The LM338 is an adjustable 3-terminal positive voltage regulator which is capable of delivering 5A over a 1.2-V to 32-V output range. The LM388 needs only two resistors to set the output voltage, this increased the popularity of LM338.
AMC7135 350mA Advanced Current Regulator
The AMC7135 is a low dropout current regulator rated for 350mA constant sink current. The low quiescent current and low dropout voltage is achieved by implementing an advanced Bi-CMOS process.
NCP3066 Constant Current Regulator
NCP3066 or NCV3066 is a monolithic constant current regulator IC used for LED lighting applications. This IC can be found in marine, automotive lighting or any portable lighting applications.
