SC7812CTG

The SC7812CTG is a low-power linear voltage regulator from Diodes Inc. It is a single channel, Constant-voltage/ Constant-current, voltage regulator with wide input voltage range from 4.5V to 25V and output voltage range from 1.6V to 17V. The SC7812CTG supports stable, accurate, low noise output state with fast transient response. The device is suitable for applications where precise, tight regulation is required.

The SC7812CTG has an operating temperature range of -40°C to 85°C with a typical dropout voltage of 0.3V @ 1A. It has an integrated shutdown mode where it can be disabled by pulling the Enable pin (EN) low to reduce its power dissipation. It also has an over-current protection feature that prevents excessive current drawing and helps to protect against accidental damage. It also has an over-temperature protection feature that will shut the regulator down if the junction temperature exceeds the maximum safe temperature of the device.

The SC7812CTG is ideal for general-purpose, low-power applications such as LED lighting and LED TV displays, battery-operated systems, automotive and industrial systems, digital isolated power supplies, communication and portable electronics, etc. The device can be used for power conditioning in HVAC, audio and video systems, automotive, industrial and home automation systems.

The SC7812CTG works according to the linear voltage regulator principle, where the device adjusts the output voltage by controlling the voltage across a pass element (transistor). The voltage at the output of the regulator is compared with the reference voltage and the error voltage is then amplified by the error amplifier. The amplified error voltage is then fed back to the pass element base to adjust it\'s voltage, so that the output of the regulator is maintained at a constant voltage level. This regulation is called \'regulating\' voltage.

The SC7812CTG is designed to provide a high level of efficiency and performance, making it an ideal choice for a wide range of applications. It has a wide input range, low power consumption and fast transient response, making it a reliable and cost-effective solution for many applications. The device is also RoHS-compliant and AEC-Q100 qualified, meaning it is suitable for use in automotive applications.
