Dual Regulated Power Supply - In this circuit, the 7815 regulatates the positive
supply, and the 7915 regulates the negative supply. The transformer should have a primary
rating of 240/220 volts for europe, or 120 volts for North America. ….(electronic

Dual Regulated Power Supply-PSU - In this circuit, the 7815 regulatates the
positive supply, and the 7915 regulates the negative supply. The transformer should have a
primary rating of 240/220 volts for europe, or 120 volts for North America. The centre
tapped secondary coil should be rated about 18 volts at 1 amp or higher,allowing for
losses in the regulator. An application for this type of circuit would be for a small
regulated bench power supply.... [Circuit by Andy Collison] |

Dual-polarity supply provides ±12V from one IC - 29-Apr-04 Issue of EDN
Well-regulated, dual-polarity power supplies find wide use in disk-drive, handheld-device,
automotive, and notebook-computer applications. In these applications, board space and
allowable component heights are continually shrinking. So, power-supply designers face the
challenge of providing split rails with as few parts as possible, thus saving board space
and cost.... [Design Idea by Keith Szolusha, Linear Technology Corp, Milpitas, CA] |

Dual-voltage regulator meets USB-power needs - 19-Aug-04 Issue of EDN This
Design Idea stems from the limited availability of IC voltage regulators that can meet key
USB-power specs, coupled with the need for turn-on sequencing and rise-time control at
each output. As always, for PC-related designs, minimum cost is a primary motivation. USB
specs require all loads to limit inrush current to less than 100 mA plus 50 µC of charge
when powered on.... [Design Idea by Wayne Rewinkel, National Semiconductor, Phoenix, AZ] |

Efficiency Characteristics of Switching Regulator Circuits - AN46 Linear
Technology Efficiency varies for different DC/DC converters. This application note
compares the efficiency characteristics of some of the more popular types. Step-up,
step-down, flyback, negative-to-positive, and positive-to-negative are shown. Appended
sections discuss how to select the proper aluminum electrolytic capacitor and explain
power switch and output diode loss calculations. |

Finesse Regulator Noise - System designers often find themselves battling power
supply hum, noise, transients, and various perturbations wreaking havoc with low noise
amplifiers, oscillators, and other sensitive devices. Many voltage regulators have
excessive levels of output noise including voltage spikes from switching circuits and high
flicker noise levels from unfiltered references....(electronic circuit added 7/03)

- I created this circuit to fix an overheating
problem with a small Chinese-made stereo set. This simple solution to a perplexing problem
worked so well that I felt the need to share it. This circuit can be used for other
applications as well...[Circuit designed by Andrew R. Morris] |

Get buck-boost performance from a boost regulator - 11-Jul-02 Issue of EDN
The SEPIC (single-ended, primary-inductance-converter] topology is generally a good choice
for voltage regulators that must produce an on output voltage that falls in the middle of
the input-voltage range, such as a 5V output from a 2.7 to 6V input, The topology has some
disadvantages, however. The efficiency of a SEPIC circuit fares worse than that of buck
and boost regulators, and SEPIC desig.... [Design Idea by Tom Gross, Linear Technology
