Frequently Asked Questions
What is the output voltage of the UA78M33CKCSE3?
The UA78M33CKCSE3 provides a fixed 3.3V regulated output voltage with a typical accuracy of ±4%, making it suitable for powering 3.3V logic devices such as microcontrollers and FPGAs.
What is the maximum output current of the UA78M33CKCSE3?
The UA78M33CKCSE3 can supply up to 500mA of continuous output current. It includes built-in thermal shutdown and short-circuit current limiting to protect the device and connected circuitry under fault conditions.
What package does the UA78M33CKCSE3 come in?
The UA78M33CKCSE3 is available in a TO-252 (D-PAK) surface-mount package, which offers good thermal performance through the exposed pad and is compatible with standard automated SMT assembly processes.
What is the minimum input voltage required for the UA78M33CKCSE3?
The UA78M33CKCSE3 requires an input voltage typically at least 1.5V to 2V above the 3.3V output, so a minimum input of approximately 5V is recommended for stable regulation under full load conditions.
Can the UA78M33CKCSE3 replace other 78M33 regulators?
Yes, the UA78M33CKCSE3 is a Texas Instruments 78M33-series device and is pin-compatible and functionally interchangeable with standard 78M33 regulators from other manufacturers in the TO-252 D-PAK package, simplifying second-source design strategies.
