• Cost-Effective Solution: Provides a reliable regulated negative voltage at a competitive price.

Additional Details

The KIA7924PI typically requires input and output capacitors for stability and transient response optimization. The input voltage should be more negative than the output voltage plus the dropout voltage. The TO-220 package allows for mounting on a heatsink to improve thermal dissipation, especially under high input voltages and output currents. Always refer to the datasheet for specific operating conditions and recommended external components.
