KA278RXXC-Series
2 A Output Low Dropout Voltage Regulators
Features Description KA278RXXC-Series (33 / 05 / 12)
• 3.3 V, 5 V, 12 V Output Low-Dropout Voltage Regulator
• TO-220 Full-Mold Package (4 Pin)
• Over-Current Protection, Thermal Shutdown
• Over-Voltage Protection, Short-Circuit Protection
• Output Disable Function The KA278RXXC is a low-dropout voltage regulator suitable for various electronic equipment. It provides a constant voltage power source in a TO-220 4-lead full-mold
package. The dropout voltage is below 0.5 V in full-rated
current (2 A). This regulator has peak current protection,
thermal shutdown, and over-voltage protection. KA278RA05C
