# Linear-regulator thermal budget
# Scope: Linear regulator DC dissipation with supplied quiescent current.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

input = 5 V
output = 3.3 V
load = 0.2 A
quiescent = 0.001 A

loss := (input-output)*load+input*quiescent [W]
efficiency := output*load/(input*(load+quiescent))

check loss budget: loss <= 0.5 W

scenario alternative: input = 4 V
