TPS773: Discrete solution to replace TPS77333DGKR

Sean Liao (Yu-Sheng)

Part Number: TPS773
Other Parts Discussed in Thread: TLV707P,

Hi sir, 

As TPS77333DGKR is too legacy and its RESET function is too unique, my customer would like to change to a discrete solution (LDO IC + RESET IC) to make the sourcing more flexible. 

Could you pls kindly suggest TI LDO + TI RESET to replace TPS77333DGKR?

Thanks a lot!

BR, 

Sean Liao

    Hi Sean,

    for the LDO I would suggest TLV707P or TLV745 if they want a PG with a similar threshold but no DELAY feature. Below is a quick spec comparison of the parts. 

    I'm going to transfer this to the VRS team for their thoughts on a supervisor with DELAY in case TPS745P does not meet their needs.

    Hi Sean,

    Adding on to Kyle's comment.

    If the output voltage is 3.3V and you need a ~220ms delay then I would recommend to look at the TPS3840DL31DBVR. This device has a 3.1V threshold which is around 94% trip point  of a 3.3V rail which is similar to the TPS773
