Give me the laws that regulate the minimum wage for California, US.
At the federal level, the minimum wage is governed by the Fair Labor Standards Act. 

Federal law currently sets the minimum wage at $7.25 per hour. 

However, federal law allows states and cities to set a minimum wage that is higher than the federal rate.  29 U.S.C. § 218(a).

California has established a higher minimum wage than the federal rate, so employers in California are required to pay the minimum wage that has been established by state law (unless an even higher rate has been established by the city or county in which they operate – see below).  Labor Code § 1182.12.

The California minimum wage is scheduled to increase gradually over time. As of 2022, the minum wage is $14.50 per hour.
