Consider a shunt linear regulator with $V_{in} = 10V$, $P_z = 500mW$, $V_z = 2.5V$ and current limiting $I_{R1(max)} = 100 mA$. Design a parallel regulator to yield a regulated output $V_{OUT} = 5.0 V$. Select correct values for $R_1$, $R_2$, and $R_3$. a) $R_1 = 50 \Omega$, $R_2 = 100 \Omega$, and $R_3 = 10 k \Omega$ b) $R_1 = 100 \Omega$, $R_2 = 37.5 \Omega$, and $R_3 = 10 k \Omega$ c) $R_1 = 100 \Omega$, $R_2 = 37.5 \Omega$, and $R_3 = 5 k \Omega$ d) $R_1 = 50 \Omega$, $R_2 = 100 \Omega$, and $R_3 = 5 k \Omega$ e) None of the above
