LX8384A General Description

The LX8384/84A/84B Series ICs are positive regulators designed to provide 5A output current. These regulators yield higher efficiency than currently available devices with all internal circuitry designed to operate down to a 1V input-to-output differential. In each of these products, the dropout voltage is fully specified as a function of load current. Dropout is guaranteed at a maximum of 1.3V (8384A) and 1.5V (8384) at maximum output current, decreasing at lower load currents.

In addition, on-chip trimming adjusts the reference voltage tolerance to 1% maximum at room temperature and 2% maximum over the 0 to 125°C range for the LX8384A, making this ideal for the Pentium P54CVRE specification. The LX8384B offers 0.8% tolerance at room temperature and 1.0% maximum over line, load and temperature. Fixed versions are also available and specified in the Available Options table below.

The LX8384/84A/84B Series devices are pin-compatible with earlier 3-terminal regulators, such as the 117 series products, but they do require input and output capacitors. A minimum 10F capacitor is required on the input and a 15F or greater on the output of these new devices for stability. Although, these capacitors are generally included in most regulator designs.

The LX8384/84A/84B Series quiescent current flows into the load, thereby increasing efficiency. This feature contrasts with PNP regulators where up to 10% of the output current is wasted as quiescent current. The LX8384-xxI is specified over the industrial temperature range of -25°C to 125°C, while the LX8384-xxC/84AxxC/ 84B-xxC is specified over the commercial range of 0°C to 125°C.
