LT1573CS8-3.3 Description

Short technical summary and product information.

The LT1573CS8-3.3 is a low dropout PNP regulator driver IC from Linear Technology, providing a cost-effective solution for high current, low dropout regulator applications. When paired with an external PNP power transistor, it can deliver up to 5A of load current with dropout voltages as low as 0.35V.

 

This device features fast transient response, minimizing the need for bulk capacitance in applications with rapid load changes. It incorporates a time-delayed latching overcurrent protection technique that does not require an external current sense resistor, protecting the regulator from continuous short circuits.

 

The LT1573CS8-3.3 offers a precision 1% output accuracy and operates from a single supply with an input voltage range of 2.8V to 10V. It is available in a small 8-pin surface mount package, suitable for space-constrained designs.

 

Key applications include microprocessor power sources, post regulators for switching supplies, high efficiency linear regulators, and ultralow dropout regulators. The fixed 3.3V output makes it ideal for 3.3V system power.
