The CJ78L15-TA is a 3-terminal positive voltage regulator manufactured by Jiangsu Changjiang Electronics Technology Co., Ltd (JCET). It is a member of the 78Lxx series of linear voltage regulators, designed to provide a fixed output voltage of 15V with a relatively low input current. Linear voltage regulators are used to maintain a stable output voltage despite variations in input voltage or load current.

Applications:

• Small Electronic Devices: Used in simple electronic projects and circuits where a stable 15V supply is needed.
• Battery-Powered Applications: Employed to regulate voltage from batteries in portable devices.
• Microcontroller Power Supplies: Provides a regulated 15V supply for microcontrollers and associated circuitry.
• Sensor Circuits: Used to power sensors and instrumentation circuits requiring a stable 15V reference.
• Educational Projects: Suitable for educational electronics projects and hobbyist applications.

Features:

• Fixed 15V Output: Provides a stable and precise 15V output voltage.
• Low Quiescent Current: Consumes minimal current when no load is present.
• Short-Circuit Protection: Includes built-in short-circuit protection to prevent damage from overloads.
• Thermal Overload Protection: Features thermal overload protection to prevent overheating.
• TO-92 Package: Available in a small and cost-effective TO-92 package for easy integration.

Benefits:

• Stable Voltage Supply: Provides a stable and regulated 15V supply for sensitive electronic components.
• Overload Protection: Protects the regulator and connected circuitry from damage due to overloads and short circuits.
• Easy to Use: Simple 3-terminal design requires minimal external components for operation.
• Cost-Effective: Offers a cost-effective solution for voltage regulation in various applications.

Additional Details:

The CJ78L15-TA is characterized by its output voltage (15V), input voltage range, output current capability (typically 100mA), and dropout voltage. It requires a small input capacitor and output capacitor for stable operation. The TO-92 package is commonly used for through-hole mounting. Detailed electrical characteristics, such as line regulation and load regulation, are usually available in the manufacturer's datasheet. Heatsinking is generally not required for low-current applications.
