TLV757P: Please help me check the best alternative

Part Number: TLV757P
Other Parts Discussed in Thread: TLV759P

Hi TIer

My customer choose a competitor's LDO which is JWH7821DFNA#TR to power up our AM6234ATCGHAALW ( TI MPU ):

The JWH7821DFNA#TR SPEC is 

Input voltage range：2.2V to 5.5V
Output voltage range：0.8V to 5V
Low conduction voltage drop：200mV Maximum at 1A
High power supply rejection ratio
-78dB at 1kHz
-42dB at 100kHz
-30dB at 1MHz
The output voltage accuracy at full temperature, full load, and full input voltage range is ±3%
Output noise 35.6uVRMS  (100Hz - 100kHz)
4.7μF The output capacitor can work stably
Over-temperature protection and over-current protection
Available in DFN3x3-8 package

At present, We hope customer to re-choose TI LDO with active discharge and fast load transient response.

And I found the TLV757P. Could you help me confirm whether this one is best suitable？

Thank you very much.

    Hi Tony,

    TLV757P would be a good option for fixed output and TLV759P would be the adjustable output alternative for the specs and active discharge. 

    The only portion where I can't confirm is on the transient response since I cannot find the competition's datasheet to have a comparison. Would you be able to share a transient response graph from the competition?

    Regards,

    Andres
