Question 1 of 27070

Q

What device is usually used as a stable reference voltage in a linear voltage regulator?

🔍 Key Concepts

• Linear voltage regulators use a reference element and a pass element • A reference voltage device should maintain nearly constant voltage over a range of current and temperature • Compare how Zener, tunnel, SCR, and varactor diodes are normally used in basic electronics circuits

💭 Think About

• Which of these components is specifically designed to hold a nearly constant voltage once it is operating in its normal region? • Which devices on the list are primarily used for switching or oscillator circuits rather than as a reference? • In a simple textbook regulator circuit, what component is usually drawn feeding the error amplifier as the fixed reference?

✅ Before You Answer

• Check the typical use of a Zener diode in power supply circuits • Identify which options are mainly switching devices (on/off control of current) • Verify which device’s IV characteristic is intentionally used to create a fixed reference voltage rather than variable or frequency‑dependent behavior
