To increase the well-known efficiency problem of linear power supply, inside a customer-made bipolar linear power supply a homemade pre-regulator circuitry is in series in front of power stage. By using constant V{sub}(DS) controlled pre-regulator, the power consumption of linear power supply...
Certain embodiments of the invention may be found in a method and system for a linear regulator with high bandwidth and high power supply rejection ratio (PSRR) and a wide range of output current. In one embodiment of the invention, the internal voltage supply of the operating circuits may be...
5. Over load protection: Auto-tripping when power supply or load has fault and output current exceeds 1.5 times of rated value. 6. Short alarm: sound & light alarm when output short-circuits. (optional) 7. Automatic off-load and discharging: when power supply shutdown, power sup...
current-mode LDO regulator that, with a higher bandwidth cur- rent loop, suppresses higher frequency noise by 49 dB (i.e., power- supply rejection) up to 10 MHz with only 68 nF at the output, which is 20 dB better than its voltage-mode counterpart. Index Terms—Current mode, dual loo...

The current-controlled pulse-width/delay circuit is supply independent and can be operated at 2.5V. The linear range of input current is from 4A to 277A, and corresponding duty cycle of pulse-width output is from 1.59% to 97.2%. The experimental results agreed with the theoretical analysis ...
Endlessly increasing power density requirements are a major driving force behind the continuous need to find new power supply solutions. Switching regulators are the top choice for high current applic
As more functionality and features are added at the transmitter, this limit becomes a problem when traditional linear regulators are used, which cannot provide any additional current. In addition, most of the power in the system using a linear regulator must be ...
The low-dropout linear voltage regulator has the advantages of being good in compatibility, low in cost, small in area, high in efficiency, low in noise, good in stability, high in power supply rejection ratio and suitable for working under no load or full load.叶乐...
