[SOLVED] How to implement mosfet with large length

[nithinp]

I'm doing a project on LDO , I was calculating the W/L ratio of pass transistor(PMOS) which turned out to be approx 8600, so I put W=4300u, L=0.5u. I'll absolutely get an error bcs the width exceeds the max width given by the foundry, How can I overcome this problem

Instead of using a single pass transistor, you can use multiple transistors in parallel.
