Question 1.
Figure 3 Assume ideal components.
Refer to Figure 3. The purpose of diode D1 is to
• provide a current path for load current when Q1 is OFF
• prevent overshoots from affecting the output
• prevent negative pulses from affecting the output when Q1 is ON
• prevent the capacitor from discharging through the transistor
Question 2.
Figure 3 Assume ideal components.
Refer to Figure 3. Assume the regulator is 80% efficient when VIN =+18 V and VOUT = +12 V. The input current is approximately
• 320 mA
• 500 mA
• 2.0 A
• 750 mA
