The LT1573CS8 is a regulator driver IC from LT, providing a low-cost solution for applications requiring high current and low dropout voltage. When paired with an external PNP power transistor, it can deliver load currents up to 5A with dropout voltages as low as 0.35V.
This device is engineered for extremely fast transient response, significantly reducing the need for bulk storage capacitance in applications with rapid, high-current load transients. It features latching overload protection, which minimizes heat sink size, and operates from a single supply with an input voltage range of 2.8V to 10V.
The LT1573CS8 is available in fixed output voltages of 2.5V, 2.8V, and 3.3V, as well as an adjustable output range from 1.27V to 6.8V. The output accuracy is better than 1%, meeting critical regulation requirements for fast microprocessors. It is housed in a small, 8-pin surface mount package designed to minimize footprint and provide adequate heat sinking.
Key features include a low-cost solution for high current, low dropout regulators, fast transient response, and latching overload protection. It is suitable for microprocessor power sources, post-regulators for switching supplies, and high efficiency linear regulators.
The typical dropout voltage is 0.35V, with capability for very low dropout below 0.2V.
The LT1573CS8 can provide a typical output current of 5A.
The output voltage accuracy is typically better than 1%.
The operating temperature range is from 0°C to 70°C.
The LT1573CS8 is available in an 8-Lead SOIC (Narrow 0.15 Inch) package.
