Frequently Asked Questions
What is the output voltage and input voltage range of the L7815CV?
The L7815CV provides a fixed +15 V regulated output. It requires an input voltage between 17.5 V and 28 V (operational range) with an absolute maximum input of 35 V. The 2 V typical dropout voltage means at least 17 V input is needed to maintain 15 V output regulation.
What protection features does the L7815CV include?
The L7815CV integrates internal thermal overload shutdown and short-circuit current limiting protection. These features allow the device to withstand fault conditions without permanent damage, making it suitable for use without external protection components in many standard applications.
What package is the L7815CV available in?
The L7815CV is available in the TO-220 through-hole package (JESD-30 code R-PSFM-T3), which supports external heatsink attachment for dissipating power in applications drawing significant load current. The three-lead package is widely compatible with existing PCB layouts designed for 78xx-series regulators.
What applications is the L7815CV commonly used in?
The L7815CV is commonly used in linear power supplies, audio amplifiers, operational amplifier power rails, instrumentation circuits, and industrial control systems requiring a stable +15 V supply. Its robust protection and proven design make it suitable for both commercial and long-life industrial applications.
Is the L7815CV compatible with other 78xx-series regulators?
Yes, the L7815CV is pin-compatible with the standard 78xx-series three-terminal linear regulator family. It uses the same TO-220 package and pinout (input, ground, output), allowing direct substitution in existing PCB designs without layout changes, as long as the 15 V output voltage matches the application requirements.
