1-07-2005 | This small but very effective circuit protects a lead-acid battery (12-V solar battery or car battery) against overcharging by a solar modul...

1-07-2005 | This circuit was developed to power an AVR microcontroller from a 12 V lead-acid battery. The regulator itself draws only 14 ?A. Of course,...

1-07-2005 | This circuit shows a way to allow normal regulators to be used in situations with higher input voltages. Although the solution consists of a...

1-12-2004 | Before you can design an adjustable voltage regulator into your circuit, or do a redesign, you need to calculate the values for two resistor...

1-07-2004 | Standard three-legged voltage regulator chips like the LM317 can cope with an input voltage of up to about 30 V, a few high-voltage types ca...

1-12-2003 | This circuit uses a step-up switch-mode regulator, which is usually used to produce a positive supply, to generate a regulated negative outp...

1-12-2003 | There are many small applications where it would be preferable to power a device directly from an RS232 (V.24) interface, avoiding a mains p...

1-07-2003 | The voltage regulators from the 78xx-series are found in many analogue power supplies. It seems, then, somewhat superfluous to say much more...

1-07-2003 | In the form of the LT1579 Linear Technology (www.lineartech.com) has produced a practical battery switch with an integrated low-dropout regu...

1-07-2003 | By combining a common 78L05 with an integrated audio amplifier of the type TDA2030, an adjustable voltage regulator can be constructed in a...
