詳細說明
Featuring fixed output voltages and multiple package options, the L7915CP is a versatile three-terminal negative regulator from the popular L79 series. This regulator is designed for local on-card regulation, eliminating distribution issues common with single point regulation. It shares the same voltage options as the L78 positive standard series, making it well-suited for split power supplies. With proper heat sinking, the L7915CP can deliver over 1.5 A output current, catering to a wide range of applications. While primarily functioning as fixed voltage regulators, these devices can also be paired with external components to achieve adjustable voltages and currents

常見問題解答
What is L7915CP?
The L7915CP is a three-terminal negative voltage regulator integrated circuit (IC) designed by STMicroelectronics. It is part of the L79 series and is capable of providing a fixed output voltage of -15V with a maximum output current of 1.5A. The L7915CP is commonly used in applications requiring a stable and regulated negative voltage supply, such as in analog and industrial circuits.
How Does L7915CP Work?
The L7915CP operates by taking an unregulated input voltage and providing a consistent, regulated output voltage of -15V. It uses internal circuitry to maintain the output voltage despite variations in input voltage and load conditions. The regulator IC dissipates excess power as heat to ensure a stable output voltage.
How Many Pins does L7915CP have and What are the Functions of the Pinout Configuration?
The L7915CP is housed in a TO-220 package and has three pins:
- Input (VIN): This pin is connected to the unregulated input voltage.
- Ground (GND): This pin is connected to the ground reference.
- Output (VOUT): This pin provides the regulated -15V output voltage.
What are the Pros and Cons of L7915CP?
Pros:
- High Output Current: Capable of delivering a maximum output current of 1.5A.
- Fixed Output Voltage: Provides a stable -15V output voltage suitable for a wide range of applications.
- Simple to Use: Requires minimal external components for voltage regulation.
- Thermal Shutdown Protection: Includes thermal shutdown and short-circuit protection for device safety.
- Cost-Effective: Offers a cost-effective solution for generating stable negative voltage supplies.
Cons:
- Heat Dissipation: May require a heat sink for efficient dissipation of excess power.
- Low Efficiency: Linear regulators like the L7915CP have lower efficiency compared to switching regulators.
- Input-Output Differential: Requires careful consideration of the input-output voltage differentials for proper operation.
Are There Any Equivalents/Alternatives to L7915CP for Recommendation?
Alternatives to the L7915CP include the MC7915 from ON Semiconductor and the UA7915 from Texas Instruments, which are also three-terminal negative voltage regulators with similar specifications.
