LD6815TD/30H,125 is a type of linear voltage regulator, which is known as a positive voltage regulator in PMIC - Voltage Regulators(Power Management Integrated Circuit). It functions to keep a stabilized output voltage while receiving the input signals that are up to the nominal specified. This low noise voltage regulator is generally used in audio processes and regulated supplies, offering high reliability and superior performance regardless of changing temperatures in the environment.

LD6815TD/30H,125 is a Voltage Regulator IC featuring a low voltage drop operating current of 125 mA and an adjustable output from 1.5V to 27V. By using Zetex Zener diodes, the device provides low noise output levels. With its high efficiency, it is suitable for use in power sensitive applications. It also features a low dropout operation with external operational amplifiers.

LD6815TD/30H,125 is commonly used in regulated power supply system, such as AC/DC rectification, post-linear regulator, DC/DC converter, and step-down transformer. The main application field is wherever fast-transient response and low noise output are needed, such as video recorders, television, microprocessor-controlled systems, audio amplifiers, and radio communications.

LD6815TD/30H,125 linear voltage regulator works by comparing the output voltage with a reference voltage and keeps both in close alignment. This is done by an internal voltage reference, error amplifier, output driver, and current limit. An incoming voltage source will be compared to the internal reference voltage during the regulation loop. When the input voltage does not equal the output voltage, the non-inverting input to the internal error amplifier will rise or fall this will cause the output transistors to turn on and off. This will then regulate the output voltage.

LD6815TD/30H,125 voltage regulator is designed to provide excellent load and line regulation. Its optimized regulation loop with its fast transient response, enables this device to provide a high precision regulated output voltage with a wide input voltage range. It utilizes a minimum number of external components for a cost-effective solution for power supply design.

LD6815TD/30H,125 features a built-in Thermal Shutdown (TSD) circuit which will automatically shuts off the regulator when the die temperature exceeds 150°C. It also features additional features such as over-current protection (OCP) and current-limit protection (CLP) in order to provide a safe operation. Furthermore, the device also includes a built-in thermal hysteresis for quick recovery from thermal conditions to reduce power dissipation.

Overall, LD6815TD/30H,125 is a highly reliable and cost-effective solution for regulated power supply systems, offering excellent load and line regulation and fast transient response. It is designed to provide stable voltage output while enabling an efficient design with minimum external components.
