Other Parts Discussed in Thread: TLV1171, LM2991, TPS795
I am not sure if this is a simple question (I am not very experienced with electronics).
I want to use the TLV4112 op amp in a circuit where it is going to pass high current >+/-300mA.
In the circuit design, I already have LDO linear voltage regulators with +5V 1A, and -5V 1A. Since TLV4112 only handles 6V max, I need to reduce this power. Is it possible to use a voltage divider (2x 1Mohm resistors) to get to +/-2.5V and use that directly as power input to TLV4112. I am not sure since I don't know the input impedance of this part.
Do I need a voltage follower as a middle stage? Or do I need two other linear voltage regulators to go to +/-2.5V?
If so, could you recommend any LDO that will supply enough current at +/-2.5V? I found (Texas Instruments TLV1171 1A positive voltage regulator), and (Linear Technology LT3015 1.5A negative voltage regulator), but these seem like an overkill for this.
Thank you very much in advance
