    5.0V-3.3V for 2-2/5A Load, Switching or LDO Regulator

    Hi everyone, I need a 5.0V-3.3V for 2-2.5A load consumption, do I need a switching regulator or LDO just fine? I prefer the simplification of LDO design but am not sure if 2-2.5A load current needs better efficiency from a buck regulator. Thank you,

    Choice of error amplifier for LDO

    Hi There! I am, for several reasons about building a adjustable LDO. Some of the specifications are: - min input voltage 4.4V - max output voltage 3.6V - 500mV dropout, due to sense resistor - wide current output range - at least 20kHz bandwidth @ 10uA load, ideally 100kHz Pass element shall...

    NPN BJT Emitter Follower - supply at Collector Current (Ic).?

    Greetings everyone, I am planning to design a current amplifier using an NPN BJT Transistor with an Emitter Follower configuration. On top of that, instead of using batteries, I am using 2 separate LDO voltage outputs as the input voltage(Vin/Vbb) to the BJT as well as the supply voltage...

    LDO crash when Lipo reaches full charge with USB still powering.

    Hello, I'm just now getting into creating PCB's as a hobby, and created a little board that simply consists of a BLE module powered by a tiny Lithium polymer battery (40mah). Since the max operating voltage of the module is 3.6V, I also have an LDO that will drop the voltage down to 3.3V...
