The LTC1517CS5-3.3#TRMPBF is a DC-DC switching regulator and categorized under PMIC - Voltage Regulators - DC DC Switching Regulators. This DC regulator comprises a switching regulator, synchronization and control circuitry, error-correction circuitry, sensing and feedback circuitry and power supply development tools. It is specially designed for computer and communication applications.

This regulator utilizes current mode control to maintain a constant output voltage, regardless of input voltage. It also employs peak current control for frequencies up to 1 MHz. Linear Technology\'s real-time peak current limiting technique limits current peaks to near zero so as to prevent overheating and to extend the life of the regulator. The integrated current sense circuit provides the peak current information to the error amplifier and the output current is limited to a maximum value of 70 mA.

The LTC1517CS5-3.3#TRMPBF is a low-noise low-dropout regulator designed for low-noise, high-performance DC-DC conversion. Its output voltage is adjustable in the range of 2.5 to 3.5V with a minimum load of 50mA. The maximum output current is 400mA, with an typical load power efficiency of 95%. ThisSwitching regulator operates over an input voltage range of 2.5V to 5.5V.

In terms of applications, this DC-DC regulator can be used for low voltage supplies for a variety of electronic products such as notebook and desktop computers, servers, industrial control equipment, telecom equipment and automotive. The special features such as low noise and high efficiency make it ideal for various power conversion solutions in industrial, medical, automotive and communications applications.

In terms of working principle, the LTC1517CS5-3.3#TRMPBF employs a switched-mode topology with synchronous rectification. The input voltage is first stepped down by an inductor, and the output voltage is regulated by an adaptive error amplifier. The switching frequency of the device can be adjusted in the range of 250 kHz to 500 kHz. The regulator contains a power switch and an enable pin that can be used to enable/disable the regulator to reduce supply current when the device is not in the use.

The regulator also provides thermal protection, over-voltage protection, under-voltage protection, current-limit protection and over-temperature protection. It also features output voltage reset, an auto-skip frequency feature and a synchronized output. The device is available in a 6-pin MSOP package that offers a low power-dissipation and long-term reliability.

The LTC1517CS5-3.3#TRMPBF DC-DC switching regulator is designed for high efficiency, low noise and reliable power conversion and designed to provide a reliable and high power density supply for low voltage applications. With its special features and advanced techniques, this DC regulator can handle reliable operation over wide temperatures.
