Part Number: LM2941
Hi all Would you mind if we ask LM2941LD? The datasheet shows that LM2941LD's ψJT is 0.2 [C/W]. Is it correct value?? Because, it seems that ψJT is small value. Kind regards, Hirotaka Matsumoto
It can sometimes be in %, other times in V/A or V/V - keep that in mind. The choice usually depends on what dominates the equation for a particular device.

Hi Philip,
The maximum dropout for LM2941 is 1 V over load and temperature. As you noted in Typical Characteristics curves, dropout is proportional to output current. The lower your output current, the lower the dropout requirement will be; therefore…
Hi Patrick,
This is an interesting schematic with an artificial GND referenced to -50 V.
First it is important to recognize that LM2941 is a 26 V device. While the Absolute Maximum rating is 60 V it is important to note that the Abs Max rating is…
Part Number: LM2941 Other Parts Discussed in Thread: TINA-TI hi, i'd like to ask you how can i measure its IQ over TINA-TI ?
reason why, its IQ would be chaged by customer configuration for it.
it'd be nice if you could measure it over TINA TI.…
Other Parts Discussed in Thread: LM2941 , LMZ21700 I am designing a Power Conversion small circuit card using the LM2941LD part. The estimated maximum output current is 0.225 amps with an input voltage of 15-19 V DC. I have selected Resistor values for…
The LM2941 is the adjustable version of LM2940. It is not designed for operation with an output voltage less than 5V.
For sure the LM2941 will behave as if it is operating in, or very near to, the dropout region: Vout may be lower than expected, Gnd…
Other Parts Discussed in Thread: LM2596 , LM2941 Hello TI,
I have a customer trying to do a design change to add start up delay to the on board power supplies to reduce inrush current at start up. The input voltage to the board is 15V.
LM2596 was…
