The LT1573CS8-2.8 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. The device features extremely fast transient response, minimizing the need for bulk storage capacitance during fast load transients.
Key features include latching overload protection that minimizes heat sink size and requires no external current sense resistor. The LT1573CS8-2.8 supports single supply operation with an input voltage range from 2.8V to 10V. It 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, with an output accuracy better than 1%.
This regulator driver is suitable for microprocessor power sources, post-regulators for switching supplies, high efficiency linear regulators, and ultralow dropout regulators. It comes in a small surface mount package, designed to minimize footprint and provide adequate heat sinking. The device operates with input voltages between 2.8V and 10V.
