KA76L05
Low Dropout Voltage Regulator
Features
Description
• Limited input voltage and high efficiency.
• Internal thermal over load protection.
• 60V load dump protection.
KA76L05 is a fixed 3-terminal low dropout voltage
regulator designed to need very low quiescent current.
Internally, implemented circuits include 60V load dump
protection, -50V reverse transient short circuit and thermal
over load protection.
• Output current up to 0.1A.
