Narrative:

We were being vectored for a visual approach to runway 25L off of the arrival. The controller had us maintaining visual separation but we were under an assigned speed. This speed caused us to get too close to the aircraft ahead (737) and we encountered their wake turbulence. In flying the approach we allowed the aircraft to get below the preceding aircraft. With the reduced separation we should have maintained our position slightly above their glide to avoid the wake. In the future I will be more diligent in assisting the pilot flying to be aware of the wake turbulence ahead. Even the best pilots may become task saturated at times and miss an important detail.
