• Manufacturer Part Number: TK11250CM
• Description: (TK112xxCM) Voltage Regulator
• Manufacturer: Toko America

* LOAD TRANSIENT
The no load voltage change can be greatly improved by delivering a little load current to ground (see right curve above)
Increase the load side capacitor when the load change is fast or when there is a large current change. In addition, at no
load, the voltage change can be reduced by delivering a little load current to ground.
