The LX8382/LX8382A-xx series ICs are positive regulators designed to provide 10A output current. All internal circuitry is designed to operate down to a 1V input-to-output differential, so the LX8382/82A can operate with greater efficiency than previously available devices. The dropout voltage for each product is fully specified as a function of load current. Dropout is guaranteed at a maximum of 1.4V for the LX8382 and 1.2V for the LX8382A at maximum output current, decreasing at lower load currents.

Fixed versions are also available and  specified in the Available Options table below. The LX8382/LX8382A-xx have 1% initial voltage reference accuracy and 2% over line, load and temperature.

The LX8382/LX8382A-xx series devices are pin-compatible with earlier 3-terminal regulators, such as the 117 series products. While a 10F output capacitor is required on both input and output of these new devices, this capacitor is generally included in most regulator designs.

The LX8382/LX8382A-xx 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 LX8382/82A-xxC is specified over the commercial range of 0°C to +125°C.
