Fairchild Semiconductor KA431SL
The KA431S / KA431SA / KA431SL are three-terminal adjustable regulator series with a guaranteed thermal stability over the operating temperature range. The output voltage can be set to any value between VREF (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 Ω.- Max Voltage : 37V
- Channels : 1
- Max Operating Temp : 85°C
- Min Operating Temp : -25°C
