Building a DC-DC Step-Down (Buck) Converter Circuit Using ...
www.egr.msu.eduthe input voltage supply. Voltage regulator also utilizes the negative feedback control loop. Some designs of voltage regulator can isolate output voltage from the input. In this application note, the LM7809 3-Terminal 1A Positive Linear Voltage Regulator will be used for building a DC-DC step-down (buck) converter circuit.
LT1175 - 500mA Negative Low Dropout Micropower Regulator
www.analog.comRegulator The LT®1175 is a negative micropower low dropout regulator. It features 45μA quiescent current, dropping to 10μA in shutdown. A new reference amplifi er topology gives precision DC characteristics along with the ability to maintain good loop stability with an extremely wide range of output capacitors. Very low dropout voltage and high

Ultralow Noise XFET Voltage References with Current Sink ...
www.analog.comimplanted junction FET (XFET) technology, voltage change vs. temperature nonlinearity in the ADR430/ADR431/ADR433/ ADR434/ADR435 is minimized. The XFET references operate at lower current (800 µA) and lower supply voltage headroom (2 V) than buried Zener references. Buried Zener references require more than 5 V of headroom for operation. The
