The LF33CV is a high performance, low dropout linear voltage regulator, designed for applications that require very low-noise output, very low quiescent power and excellent line and load regulation. The voltage regulator has many advanced features, such as internal current limiting, frequency compensation, thermal shutdown and output short-circuit protection. It is ideal for use in a wide variety of linear applications, including battery supplies, portable and automotive equipment, as well as personal computer power supplies.

The LF33CV is a three-terminal low-dropout positive voltage regulator that can regulate a wide input voltage range of 2.5V to 18V with a 1.5V to 35V output voltage range. It is designed with advanced biasing, low power, and improved line regulation features. It is ideal for use in battery-powered systems, such as notebook and laptop computers. The output voltage can be trimmed to a pre-set value using external resistors. It is also designed to eliminate the need for an external feedback compensation component.

The LF33CV has an adjustable, low-noise, low quiescent current, low-dropout voltage regulator that offers precise voltage regulation. It provides architecture and loop stability without the use of an external compensation circuit, making it ideal for space-constrained applications. The output voltage can be adjusted by using two external resistors, with a maximum deviation of ±2%. The output voltage can be selected from a range of user-defined values, up to an input voltage of 18V. The current limit threshold is adjustable through the addition of an external resistor. The quiescent current and no-load voltage drop are minimized to very low levels.

The relatively low dropout voltage makes the LF33CV suitable for battery-powered applications, where longer battery run time is important. The high efficiency, low quiescent current, and low dropout voltage make the LF33CV an ideal choice for systems that require low heat dissipation and long battery run time. The device is also designed to reduce EMI generation and offer good filtering performance. It provides stable operating conditions with minimal line and load transients.

In addition, the LF33CV offers superior thermal shutdown and over-temperature protection. The thermal shutdown circuitry protects against thermal overloads, while the over-temperature protection circuitry monitors the junction temperature and shuts down the device if the junction temperature exceeds the thermal limit. Both circuits are designed to prevent thermal damage during extreme operating conditions.

The LF33CV is a high-performance, three-terminal, low-dropout linear voltage regulator. It provides excellent performance for low-noise applications, along with flexibility in output voltage trimming, current limiting, and thermal protection. Its high-efficiency, low-noise, low-dropout operation makes it ideal for use in battery-powered applications that require long battery run time and good filtering performance. Its superior thermal shutdown and over-temperature protection features make the LF33CV the perfect choice for linear voltage regulator applications.
