L I N D O C # 8383 LX8383-xx/8383A-xx/8383B-xx 7.5A LOW DROPOUT POSITIVE REGULATORS PR O D U C T I O N DATASHEET The LX8383/8383A/8383B series ICs are positive regulators designed to provide 7.5A output current. All internal circuitry is designed to operate down to a 1V input-to-output differential, so the LX8383/ 83A/83B 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 1.3V for the LX8383A/83B and 1.5V for the LX8383, at maximum output current, decreasing at lower load currents. Fixed versions are also available and specified in the Available Options table below. The LX8383B offers a tighter voltage reference tolerance initial accuracy and 1% over line, load and temperature. The LX8383/83A have 1% initial accuracy and 2% over line, load and temperature. The LX8383/83A/83B 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. The LX8383/83A/83B 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 LX8383I/8383AI is specified over the industrial temperature range of -25°C to +125°C and the LX8383C/8383AC/8383BC is specified over the commercial range of 0°C to +125°C.
