PMIC - Voltage Regulators - Linear

The LT3020EMS8#TRPBF is a monolithic low noise, low quiescent current, high voltage linear voltage regulator. It is designed to regulate a wide range of supply voltages between 2.5V to 40V, and it offers very low dropout voltage, making it especially suited for powering sensitive loads from low dropout voltage supplies. The LT3020EMS8#TRPBF has a maximum output current of 2.5A. In addition, it provides a low dropout voltage of 50mV at 1A load current. The device is well suited for portable battery-powered applications that require low quiescent current and high output current.

The LT3020EMS8#TRPBF employs a current-mode architecture with a fixed gain or adjustable gain topology that enables the output voltage to be regulated with low output voltage ripple. It also features a high slew rate of up to 4A per microsecond, which provides fast transient response to supply load changes. The combination of low noise and high slew rate ensure that the LT3020EMS8#TRPBF can support high output current, even with very high input voltage and wide output voltage range.

The LT3020EMS8#TRPBF is designed for environments that require low quiescent current, high output current and low output noise capabilities. This device is well suited for powering a variety of mobile and embedded applications, including smart phones, tablets, LCDs, power supplies, wireless sensors, and other complex systems that require a low noise, low quiescent current linear regulator with high output current capability.

The working principle of LT3020EMS8#TRPBF is based on the voltage regulation control (VRC) architecture. In this architecture, an output voltage control loop is used to monitor and adjust the output voltage as required. The LT3020EMS8#TRPBF uses a voltage divider as the voltage sensing element to monitor the output voltage, and an error amplifier to compare the set point voltage with the measured voltage and generate an output voltage control signal. The output voltage control signal is then used to adjust the gain of the voltage regulator, providing the required output voltage regulation.

The LT3020EMS8#TRPBF also features low quiescent current and wide range of operating frequencies to maximize efficiency and reduce circuit size. In addition, the device can be programmed to provide an external frequency compensation pin that ensures the regulator operating frequency is optimized without relying on external components.

The combination of low noise, low quiescent current, high output current and wide operating range make the LT3020EMS8#TRPBF suitable for a wide range of applications. It can be used to provide regulated power to sensitive loads, such as mobile phone baseband, power amplifiers and processors, or other embedded applications that require low noise operation and high output current capability.

In summary, LT3020EMS8#TRPBF is a monolithic low noise, low quiescent current, high voltage linear voltage regulator, suitable for a wide range of applications. It is designed for environments that require low quiescent current, high output current and low output noise capabilities. The device employs a current-mode architecture with a fixed gain or adjustable gain topology, and provides fast transient response to supply load changes. The combination of low noise and high slew rate enable the LT3020EMS8#TRPBF to support high output current, even with very high input voltage, and wide output voltage range.
