CAT6219-330TDGT3, is a low drop-out (LDO) adjustable voltage regulator, which is specifically designed for regulating linear power supply in portable electronic devices, such as smartphones, tablets, laptop computers, etc.

CAT6219-330TDGT3\'s application field lies in mobile devices and other the requirements for low output current. It can outputs 1.5A with continuous operation and peak output current up to 3A. It is able to offer 3V to 6V adjustable output voltage for different loads, and it also provides output voltage short-circuit current protection, thermal shutdown protection, output overvoltage protection, as well as reverse current protection. The ripple rejection ration of CAT6219-330TDGT3 is up to 65dB, which makes it ideal for systems requiring low noise output to deliver current and maintain quality system performance.

The working principle of CAT6219-330TDGT3 is based on a standard linear regulator. It uses an internal reference voltage and two power transistors to control the output stage, which is constructed with a common emitter configuration. The input voltage is coupled to the series pass transistor, which acts as the current driver of the output stage. This series pass transistor keeps the output voltage constant in the event of a change in load current. The reference voltage establishes the output voltage. When the output voltage is lower than the reference voltage, the pass transistor increases current by applying more voltage to the base of the pass transistor, allowing more current to flow from the input voltage to the output voltage.

CAT6219-330TDGT3 supports a wide range operating temperature from -40° C to +85° C. It is RoHS compliant, Lead Free. There are both SOP-5 and DPM-3 packages for CAT6219-330TDGT3. It requires only few external components for its operation, and includes shutdown, output voltage setting and output overcurrent protection, making it easy to be integrated into applications with minimum layout effort. With its low dropout voltage, low quiescent current and high PSRR, CAT6219-330TDGT3 can be widely used to provide linear regulated output voltage in portable electronic devices.
