Jade,
For LM78 and UA78, we don't have this data. These are linear regulators and legacy devices and PSRR was not characterized for these devices.
LM2940 and TLV761 have graphs with the values of PSRR that you need.
LM2940:
TLV761:

Hi, Does this LDO support -40℃? The absolute maximum rating is -65℃. However, the recommended operating temperature is 0℃. Could you tell me this reason? And Does this device get the following data? Customers want to know the relationship…
Part Number: UA78 Dear TI ‘s engineer,
there is a customer ask for a question about that how much is the temperature of UA78M12C thermal overload protection? from the datasheet just show the device has internal thermal overload protection,and the…
Part Number: UA78 Hi sir,
What are the differences between UA7805CKCS, UA7805CKCSE3, and UA7805CKCT. I only know UA7805CKCT has the different package of TO-220(KCT). What about UA7805CKCS and UA7805CKCSE3?
Thanks.

Part Number: UA78 Hello,
Customer is using the UA7812CKCS whose min operating temperature is 0C. The customer needs to know the consequences of using this device in an environment that's -40C. Is there a part that's rated for that temperature?…
Part Number: UA78 I have a problem when powering on with TI UA7815 while applying unregulated 20V DC to the input . The +15V (A21-3) from UA7815 will have about 10ms delay compare to -15V(A22-3) from the scope shot below. Is there anyone know what caus…
Part Number: UA78 Other Parts Discussed in Thread: LM2674 Hi Team,
My circuit is 15Vin and 5V output with output current 0.3A. The ambient temperature is 25C. There is no hot sources around UA7805.
The UA7805 measured top temperature is about 125C. Is…
Part Number: UA78 Hello,
I have made small power supply of 15V using 7815. A 230V to 18V transformer followed by a bridge rectifier and followed by a filter. The output of the filter is given to 7815. A capacitor is also used after 7815. The circuit is…
