Part Number: TLV4112 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…
Hi Jim,
Thank you for all of the information! Would it be possible to post a scope shot with Vin, Vout, EN, and Iout? This will help give a better indication of what is going on.
Increasing the input capacitor will help the upstream device supply…
Hi Daniel,
Thanks for the inquiry here on E2E. Not seeing your specific details or block diagram, I'll start out with some suggestions and we can refine the design from here.
First, for the 5V switch, please look at the LM34904: http://www.ti.com…
Other Parts Discussed in Thread: TPS7A7100 , TPS795 HI,
I need low drop voltage regulator adjustable 0.5A output: Vin is between 4.8-5.2V (USB host voltage), and Vout need to be minimum of 4.65-4.7 (the higher the better.....)
there is the TPS79501, but…
Hi Bill,
board supply is +5V to +6V from a DC/DC converter. To reduce supply noise I’m going to use a first LDO to create a voltage around +4.3 V, then two LDO to create +3.3V analogue (Iout 200 mA low noise required) and +3.3V digital (Iout 50 mA).…

Question/Problem:
At what Vin-Vout does PSRR start falling?
Answer:
For a PMOS pass element based LDO, the PMOS FET provides some gain to the loop which is directly proportional to PSRR. As Vin approaches Vout…
