LM3940 IC – 1A – Low Dropout Regulator IC
The LM3940 is a 1-A low-dropout regulator designed to provide 3.3 V from a 5-V supply.
The LM3940 is ideally suited for systems which contain both 5-V and 3.3-V logic, with prime power provided from a 5-V bus.
Because the LM3940 is a true low dropout regulator, it can hold its 3.3-V output in regulation with input voltages as low as 4.5 V.
The TO-220 package of the LM3940 means that in most applications the full 1 A of load current can be delivered without using an additional heat sink.

LM675T
The LM675 is a monolithic power operational
amplifier featuring wide bandwidth and low input
offset voltage, making it equally suitable for AC and
DC applications.
The LM675 is capable of delivering output currents in
excess of 3 amps, operating at supply voltages of up
to 60V. The device overload protection consists of
both internal current limiting and thermal shutdown. Figure 2. Non-Inverting Amplifier The amplifier is also internally compensated for gains
of 10 or greater.
