The LM317 is a floating regulator meaning there is no device ground terminal. Quiescent current flows to the load instead of being wasted flowing to ground. Regulated output voltage of hundreds of volts is possible if the maximum input to output differential does not exceed 40-V at any time....
Therefore, the study of large output current, high stability LDO has certain meaning in both theory and practice. 因此,对大电流、高稳定性的LDO线性稳压器的研究具有一定的理论和现实意义。 www.fabiao.net 5. Through systematic analysis of LDO, the loop will be more stable after adopting appropriate...
CAT6243 LDO Voltage Regulator - Adjustable CMOS 1A Description The CAT6243 is a low dropout CMOS voltage regulator providing up to 1000 mA of output current with fast response to load current and line voltage changes. CAT6243 offers a user adjustable output voltage from 0.8 V to 5.0 V and ...
If voltage drops by 10 % you'll get 4.05 V and current drops by some 50 % meaning that you need rather full batteries to get a reasonable amount of light from your LED. First idea is to put a voltage regulator between the batteries and the circuit and adapt the resistor to its output...

What is Spreading Inductance?The spreading inductance of a plane pair has a simple meaning, but it can be difficult to calculate. Here are some points designers should know about the spreading inductance of a plane pair.Read Article Ebook: PDN Simulation and Analysis GuideIn this e-book, we’...
meaning the error amplifier pole location can be ˜1 Hz (assuming 10-20 pF compensation capacitor). At close to no load, this is a severe problem when the output pole (formed by the load impedance and output capacitor at the output node of the LDO) overlaps with the internal pole locat...
10.3.10 WAKE Pin The WAKE pin is a high-voltage reverse-blocked input used for the local wake-up (LWU) function. This function is explained further in Local Wake-Up (LWU) via WAKE Input Terminal section. The pin is defaulted to bi- directional edge trigger, meaning a local wake-up ...
