LX8382-00CV IC REG LIN POS ADJ 10A TO247-3 Microsemi Corporation

 

DESCRIPTION

The LX8382/8382A 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 LX8382/82A have 1% initial voltage reference accuracy and 2% over line, load and temperature.
The LX8382/82A series devices are pin-compatible with earlier 3-terminal regulators, such as the 117 series products. While a 10µF output capacitor is required on both input and output of these new devices, this capacitor is generally included in most regulator designs.
