The LT3008EDC-1.8#TRMPBF is a low noise, low dropout linear regulator. This paper will provide an overview of its application field and working principle.

The LT3008 empowers low power design in a wide range of applications. It is especially suitable if a reliable low voltage, constant current or voltage source is required in a limited space and when performance improoves are necessary. Potential applications and use scenarios include, but are not limited to, smart lighting and tablets, as pico-dwelling environments, automation and instrumentation, automotive and medical electronics.

The LT3008 uses current-mode architecture for regulating output voltage, regulating both current and dropped voltage. Its unique design reduces the need for external components, providing superior transient response, fast loop response and high accuracy. In addition to a wide input voltage range of 2.5V to 28V, it provides a low output dropout voltage, making it suitable for 3.3V and 5V system.

The expression of the LT3008EDC-1.8#TRMPBF can be compared to other voltage regulators forming the PMIC (Power Management Integrated Circuit) family being focused in Linear Voltage Regulators, concerning the fact that this type of regulator is constituted by an electronic component which is usually a voltage regulator embedded in an integrated circuit enabling the regulation of the output voltage, by relying on the differences between input and output voltages, as these regulators work on the basis of restricting current flow.

For the case of the LT3008EDC-1.8#TRMPBF its main features are, a low input voltage capability (2.5V), 400 µA of quiescent current, extremely low noise, as low as 10 uV RMS, and a wide load dynamic range. It has an output voltage range of 0.6V to 28V, making it suitable for smart lighting, tablets and other applications, and is available in an 8-pin DFN package.

The working principle of the LT3008EDC-1.8#TRMPBF is based on the linear architecture, using the current-mode (CM) design technique. This technique offers high line and load transience response against output transients, with little EMI and low output noise. This regulator also offers fast loop response and high accuracy, making it suitable for a wide range of applications.

The LT3008EDC-1.8#TRMPBF is designed to be flexible, allowing the voltage to be adjusted through the use of an enable pin that controls the voltage of the output. This allows the output voltage to be adjusted for optimal performance with specific loads or environmental conditions.

The LT3008EDC-1.8#TRMPBF also provides excellent thermal performance, with very low thermal dissipation while operating because its on-chip design reduces power consumption. Its external components are low-cost, so the cost of production is kept low. Its long life performance is maintained through its bi-directional current limit and over-temperature protection.

In summary, the LT3008EDC-1.8#TRMPBF provides low noise, low dropout linear regulators, with a wide input voltage range, high accuracy, low component count, and high thermal performance. Its current mode technology ensures excellent line and load transient response, with low EMI and output noise. Its enable pin allows for flexibility in output voltage, with the benefits of long life and low cost of production. All of these features make the LT3008EDC-1.8#TRMPBF a great choice for power system design in a wide range of applications, such as smart lighting, tablets, and other applications.
