DATASHEET and Circuit Diagram

The picture shows simplified application circuit diagram of the MC34710 produced by Freescale Semiconductor. According to the datasheet, you will get such the following benefits from this device: powering multi-voltage MCUs solution, built-in protection features, simple circuit, low cost 32-pin thermally enhanced SOICW package.

LM723 Voltage Regulator IC families has been known widely for building power supply regulators. The following circuit diagrams typical apllication using LM723C as a 12V, 500mA (a small bench power supply).

This is a Current Boost Regulator Circuit Diagram using the 78xx fixed voltage regulator. You can use sort of 78xx devices such MC7800 Series from Motorolla Analog IC to install the circuitry.

Current Boosted the MC7800 series with PNP transistor, you can use 2N3055 / MJ2955 Complementary Silicon Power Transistors that will produce current to [...]

In this article you can find LM5118 Basic Buck-Boost Regulator features such as Ultra-wide input voltage range from 3V to 75V, Smooth transition between buck and boost modes, Oscillator synchronization capability, Enable input wide bandwidth error amplifier, and etc.

Since the LM78xx series are available at several fixed output voltages for the three terminal positive regulators type, this device can be used in the wide range applications such as logic systems, instrumentation, HiFi, and other solid state electronic equipment.
