LM358: question

Allan Fan

Part Number: LM358
Other Parts Discussed in Thread: TLV9002

Hi Expert,

Customer tried LM358 and expect to have 3.7Vo at least with 200ohm load, so 20mA seems ok. But now they only get about 3V. Would you please have a look below schematic and let us know what might be wrong? Or please suggest us other solutions. By the way, they need -40 - 85degC solution.

Thanks.

Regards,

Allan

Hi Allan,

the schematic didn't come through. Please post again :-)

Maybe this datasheet snippet can already help:

Hi Kai,

Updated the schematic.

Customer 's load is only 200ohm. Please help check schematic if anyway can make it to fulfill customer's need 3.7V or suggest other suitable solution.

Thanks,

Allan

Alan,

TLV9002 will have a higher positive output voltage.
