The LX8384/84A/84B Series ICs are available and specified in the Available positive regulators designed to provide 5A Options table below. output current. These regulators yield The LX8384/84A/84B Series devices are higher efficiency than currently available pin-compatible with earlier 3-terminal devices with all internal circuitry designed regulators, such as the 117 series products, to operate down to a 1V input-to-output but they do require input and output differential. In each of these products, the capacitors. A minimum 10µF capacitor is dropout voltage is fully specified as a required on the input and a 15µF or greater function of load current. Dropout is on the output of these new devices for guaranteed at a maximum of 1.3V 8384A stability. Although, these capacitors are and 1.5V 8384 at maximum output generally included in most regulator current, decreasing at lower load currents. designs.

In addition, on-chip trimming adjusts the LX8384/84A/84B Series quiescent reference voltage tolerance to 1% maximum current flows into the load, thereby at room temperature and 2% maximum over increasing efficiency. This feature contrasts the 0 to 125°C range for the LX8384A, with PNP regulators where up to 10% of the making this ideal for the Pentium P54C- output current is wasted as quiescent VRE specification. The LX8384B offers current. The LX8384-xxI is specified over tolerance at room temperature and the industrial temperature range of -25°C to maximum over line, load and 125°C, while the LX8384-xxC/84Atemperature. Fixed versions are also xxC/84B-xxC is specified over the
commercial range of 0°C to 125°C.
