Introduction

LT3063HDCB#TRMPBF (hereinafter referred to as LT3063) is a monolithic Low Dropout (LDO) voltage regulator developed by Linear Technology Company. The device is designed for applications where low noise and fast transient response are desired. LT3063 can be used in processor core, memory, FPGA, and high current LED applications.

Specifications

LT3063 is available in output voltage options ranging from 0.8V to 5.5V in 100mV increments, with load regulation of 0.1%. The standard input voltage range is 3.6V to 10V, and the maximum output current is 5A. The frequency response of the device is 25uV/us, the quiescent current is 1.3mA and the dropout voltage is typically 410mV. The device also features reverse current protection, over temperature protection, and a built-in soft-start circuit.

Application Field and Working Principle

LT3063 is primarily used in processor core and memory applications. It can supply a stable output voltage for a wide range of processor cores, including low-power cores such as Atom and Cortex A7, mid-power cores such as Core i3 and Intel Xeon, and high-power cores such as Core i7 and Xeon E5. It is also ideally suited for memory applications such as DDR3, DDR4 and LPDDR3. In terms of working principle, LT3063 utilizes a dual-voltage, single-stage topology to achieve low dropout performance and fast transient response. It incorporates an internal PMOS current source with a regulated current reference, thus providing high PSRR, low quiescent current and fast transient response. The reduce ripple at the input of the LDO, LT3063 utilizes a loop filter which is optimized for good line rejection. The loop filter also provides good noise rejection and output stability. Finally, the LDO is protected with an over temperature protection circuit which limits the output current when the junction temperature exceeds its limit.

Advantages

LT3063 offers several advantages over traditional linear voltage regulators. Firstly, it features low dropout, which allows it to maintain a stable output voltage even at low input voltage. Additionally, it features high PSRR, resulting in low output noise even at high frequency switching, and fast transient response. It also has a low quiescent current and reverse current protection which prevents the device from current backflow. Finally, it incorporates an over temperature protection circuit which limits the output current, thus protecting the device from being damaged due to unusually high load current.

Conclusion

LT3063 is an excellent choice for processor core, memory, FPGA, and high current LED applications. It features low dropout performance, fast transient response, and high PSRR, making it well suited for processors and memories. Additionally, it is protected from current backflow, over temperature and has a built-in soft-start circuit. Overall, LT3063 is an ideal choice for applications requiring low noise and fast transient response.
