Linear Voltage regulators are some of the most practical, reliable and affordable solutions when it comes to providing a consistent supply of electrical power. Among many others, the L7915CT voltage regulator stands out due to its wide range of application fields and great efficiency.

Features

The L7915CT is part of a family of voltage regulators from STMicroelectronics that also includes popular solutions such as the L7815CT, L78L15CT and the L78L05CT. All of them offer several features that make them an excellent choice for many applications:

• High stability, great tolerance for transient fluctuations, noise and other disturbances
• Low power dissipation and low noise
• Wide range of input and output voltage options
• Thermal overload protection
• Maximum temperature rating of +125°C

The L7915CT is especially versatile and it can be used in a wide range of projects and applications, including power supplies, on-board and off-board battery charging, low-noise audio amplifiers.

Working principle

Like most linear voltage regulators, the L7915CT works by regulating the output voltage using a feedback control system. This system is composed of a comparator, generator and an error amplifier, whose job is to detect any changes on the output voltage, create a signal and adjust the reference voltage in order to keep it steady.

The whole process is based on the comparison between the reference voltage and the output voltage, whose result is then amplified before being transmitted to the regulator. This amplifying signal ‘tells’ the regulator to increase or decrease its power with the objective of maintaining the output voltage at its desired value.

This simple but effective solution can handle a wide range of output voltages (from 5 to 15V), while also allowing a wide range of input voltages and current values. This makes the L7915CT an ideal solution for many scenarios.

Conclusion

The L7915CT is one of the most popular linear voltage regulators available in the market, mainly because of its versatility and ease of use. Its wide range of input and output voltage options, combined with its low power consumption and great noise tolerance, make it suitable for almost any project. Furthermore, its feedback control system is reliable and presents no risks of over voltage or over current.
