LT1573 is a low cost, high current, low dropout, fast transient response regulator driver IC that can be used with an external PNP power transistor to provide up to 5A of current with a dropout voltage as low as 0.35V. The device 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. Base drive is limited for instantaneous protection, and a time-delayed latch protects the regulator from continuous short circuits. The LT1573 is available in both adjustable and fixed versions with a operating voltage range of 2.8V to 10V.
