Introduction
This is a three-terminal adjustable shunt voltage regulator whose output voltage can be set to any value between the reference voltage (approximately 2.5V) and 36V using two external resistors. The device features an output impedance of 0.15Ω (typical). Its active output circuit provides a very sharp turn-on characteristic, making it an excellent replacement for Zener diodes in many applications. These applications include on-board voltage regulation, adjustable power supplies, and power switching.
Features
- Adjustable output voltage range: 2.5V ~ 36V
- Low dynamic output resistance: 0.15Ω (typical)
- Low temperature drift: 5mV (typical)
- Low output noise
- High capacitive load stability
- Current capacity range: 1 ~ 100mA
Applications
- Adjustable voltage and current reference
- Zener diode replacement
- Voltage monitoring
- Comparator with integrated reference
- Secondary-side voltage regulation for flyback switching power supplies
