FEATURES
s s DESCRIPTIO s s s s s s s Low Cost Solution for High Current, Low Dropout Regulators Fast Transient Response Needs Much Less Bulk Capacitance Latching Overload Protection Minimizes Heat Sink Size Precision Output Voltage (1%) Single Supply Operation: VIN = 2.8V to 10V Small Surface Mount Package Capable of Very Low Dropout Voltage (<0.2V) Fixed or Adjustable Outputs Shutdown The LT ®1573 is a regulator driver IC designed to provide a low cost solution for applications requiring high current, low dropout and fast transient response. When combined with an external PNP power transistor, this device provides load current up to 5A with dropout voltages as low as 0.35V. The LT1573 circuitry is designed for extremely fast transient response. This greatly reduces bulk storage capacitance when the regulator is used in applications with fast, high current load transients. To keep cost and complexity low, the LT1573 uses a new time-delayed latching overcurrent protection technique that requires no external current sense resistor.
