TPS748A: Line- and Load-Transient Response

Sebastian Ausserwoeger

Part Number: TPS748A
Other Parts Discussed in Thread: TPS74801-Q1

Hi,

we are considering to use TPS748A in an upcoming project, since it has excellent accuracy and PSRR combined with a programmable soft-start time. Unfortunately, the part datasheet does not provide any information regarding line- and load-transient response. This seems somewhat odd, since this data is usually included in TI's LDO datasheets. Looking at both datasheets, the TPS748A seems to be quite similar to the TPS74801-Q1 but of course we cannot be certain that transient performance is similar too.

Can you provide any additional information regarding line- and load-transient performance of the TPS748A or can you confirm that it is similar to the TPS74801-Q1?

Thanks in advance.

Best regards,

Sebastian
