Follow the source / drain labeling on the silkscreen and you can use most TO-92 MOSFETS - the package drawing reflects enhancement mode BS170s, depletion mode LND150s will be reversed. R2 gate bias to ground, R1 gate bias / feedback to drain, R3 drain, D1 gate protection diode. For BS170 use 2M2 or 4M7 R1&R2, 4K7 or 10K R3, D1 1N4739. For LND150 omit R1, use 1M R2, 4K7 R3, omit D1. C1 & C2 are to taste, I like 22n to 100n.
