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 (Vcc/Vsupply) to the BJT respectively.
LDO Vin = 3.3V ; 60mA
LDO Vsupply = 5V ; (=<200mA)
Amplified output needed = 2.6V ; 6A
So, my question is, in order to get that output current (6A) which is the Emitter Current (Ie), do I need to supply to collector current (Ic) with ~6A current supply of 5V LDO? Or can I supply to the collector current (Ic) with about the same as 60mA (Ib) because the function of the BJT(of this application configuration) is to apply gain (Beta) to the input currents themselves, (Ib & Ic) ?
Please do correct me if I understand the working principles wrongly.
And, thank you all in advance!
