Description
The K033B033 is a CMOS-based voltage regulator IC with high output voltage accuracy, low supply current, low dropout, and high ripple rejection. It consists of a voltage reference unit, an error amplifier, resistors for setting the output voltage, a current limit circuit, and a chip enable circuit. The K033B033 performs with low dropout voltage due to built-in transistor with low ON resistance, and the chip enable function prolongs the battery life of each system. It is suitable for power supply in handheld communication equipment. The output voltage is internally fixed with high accuracy, and it is available in SOT-23-6, PLP1820-6, and WL-CSP-6 packages.
