LMD18200: Can I replace LMD18200 with LMD18201? LMD18200 is not available in market currently.

Part Number: LMD18200
Other Parts Discussed in Thread: LMD18201

LMD18200/NOPB in short supply.

LMD18201/NOPB is available.

My design does not use the current sense pin. Can I use LMD18201 in place of LMD18200?

Thanks,

Hello,

Will you be modifying your PCB? Pin 8 is a signal GND for the 18201. It should be grounded. Not sure what your connection is today on the 18200.

LMD18200 has pin 8 connected to 2.2K resistor (0.1 uF capacitor is in parallel with the resistor).

Where can we find LMD18200?

Pragnesh,

There are 93 pcs LDM18200 on RS components

If I use 0-ohm resistor to replace 2.2K resistor on pin 8 of LMD18200, can I use LMD18201? Or the performance is not comparable?

Pragnesh,

If you don't need the current sensing output from LMD18200, yes, you can use 0-ohm resistor to put pin 8 to ground and use LMD18201.
