STMicroelectronics L7815CP Linear Voltage Regulator 15V 1.5A TO-220FP

Reliable Voltage Regulation with STMicroelectronics L7815CP

The STMicroelectronics L7815CP is a high-performance linear voltage regulator designed to deliver precise 15V output with exceptional stability and efficiency. Part of the renowned L78xx series, this TO-220FP packaged IC combines robust performance with integrated protection features, making it an ideal choice for demanding power management applications. With its ability to handle up to 1.5A output current and operate across a wide input voltage range (up to 35V), this regulator provides engineers with versatile design capabilities for industrial, automotive, and consumer electronics projects.

Key Performance Specifications

At its core, the L7815CP maintains a fixed 15V output with ±2% accuracy across operating conditions. The device operates efficiently with a maximum dropout voltage of just 2V at 1A load, ensuring minimal power dissipation even under varying input conditions. Its 35V maximum input voltage rating provides ample headroom for applications with fluctuating power sources, while the integrated 8mA quiescent current draw optimizes efficiency in low-power systems.

Advanced Protection Architecture

Engineered for reliability, the L7815CP incorporates comprehensive protection mechanisms including thermal shutdown and output current limiting. These features create a robust defense against common failure modes, ensuring device longevity in challenging environments. The thermal protection system automatically reduces output current when temperatures exceed safe operating limits, while the short-circuit protection maintains stable operation during fault conditions.

Industrial-Grade Design

Housed in a TO-220FP package, this regulator combines industry-standard footprint compatibility with enhanced thermal performance. The through-hole mounting configuration ensures reliable mechanical stability and heat dissipation in high-vibration environments. Operating temperature range from 0°C to 125°C makes it suitable for deployment in both commercial and industrial applications, maintaining performance across demanding thermal cycles.

Applications and Implementation

The L7815CP's versatility shines in various applications including precision power supplies, industrial control systems, automotive electronics, and consumer devices. Its 54dB PSRR (120Hz) specification ensures clean voltage output in noise-sensitive applications like audio equipment and measurement instruments. Designers appreciate its ease of implementation requiring only minimal external components, typically just input/output capacitors for stability.
