LDO Controller allows the use of a low cost pass transistor for the I/O supply 8-Pin SOIC bines switching and linear controller Internal pre-regulator eliminates cross talk between switching and linear regulators Automatic shut down of the linear regulator when connected to the Vcc2 detect pin On-Board MOSFET Driver Fastest transient response of any controller method (0 to 100% Duty Cycle in 100ns) 1% Internal Voltage Reference Internal Under-Voltage Lockout protects MOSFET during start-up The IRU3033 IC bines a switching controller and a linear regulator controller all in a pact 8-pin surface mount package, providing a total solution for dual supply processor applications such as an Intel P55C™ , AMD K6™ , as well as Cyrix 6X86L™ and the M2™ processors.
Typically in these applications a dual supply regulator converts 5V to 3.3V for I/O supply and a jumper programmable supply of 1.25V to 3.5V for Core supply.
The linear regulator controller portion in the IRU3033 is a programmable controller allowing flexibility for the I/O regulator and has a minimum of 50mA drive current capability designed to provide ample current for an external pass transistor.
