Q. Fixed Voltage Regulators ?
Positive voltage regulator series with seven voltage options - IC 7800 Series
The 7800 series consists of three - terminal positive voltage regulators with seven voltage options. The last two numbers "00" represents the output voltage of the regulator. These ICs are designed as fixed voltage regulators and with adequate heat sinking can deliver output currents in excess of 1A. These ICs also have internal thermal overlaod protection and internal short-circuit current limiting.As shown in figure, proper operation requires a common ground between input and output voltages. In addition, the difference between input and output voltages (Vin - Vo), called dropout voltage, must be typically 2.0 V.
A second-order process with one pole at the origin has the transfer function 3/(s(2s + 1)) Find the output as a function of time, for a unit step input change. Sketch the expected
