LTC1530CS8-1.9#PBF Application Field and Working Principle

The LTC1530CS8-1.9#PBF is a 1A low-noise, low-dropout, CMOS, micropower, wide-input-range, bipolar linear regulator specifically designed for use in under-the-hood automotive automotive, industrial, and consumer applications. This regulator has a CMOS core, which provides low dropout voltage, very low quiescent current, low output noise, high PSRR, and low output voltage ripple. Additionally, the LTC1530CS8-1.9#PBF offers enhanced device reliability with overvoltage protection and overcurrent protection.

Application Field

The LTC1530CS8-1.9#PBF is especially suited for use in many automotive and industrial environments, allowing systems to operate reliably in a wide temperature range and in regions with an uneven power supply. The device operates with an input voltage range of 4.5V to 36V and offers an adjustable output voltage of 0.6V to 10V. This makes it suitable for a variety of applications that require efficient conversion from unregulated power sources like batteries and secondary supplies to regulated voltages. Typical applications include automotive body electronics, factory automation, heating, ventilation, and air conditioning (HVAC), consumer electronics, and household appliances.

Working Principle

The LTC1530CS8-1.9#PBF is designed to deliver a regulated output voltage with a minimum of effort and noise. The device\'s power scheme consists of two parts: the output voltage is set by a voltage divider connected to the device\'s VFB pin, and the linear regulator section regulates the output in order to maintain its set voltage. A combination of current and voltage foldback maintain device stability and prevent output voltage overshoot.

The combination of voltage, current, and temperature feedback make the LTC1530CS8-1.9#PBF a very reliable device. It is fully protected against input voltage overshoots, current limiting, and thermal shutdown, which make it ideal for use in automotive and harsh industrial environments. The device\'s operating frequency is optimized for very low output noise, making it suitable for use in high-end audio/video applications.
