1 / 7 page DESCRIPTION KEY FEA TURES The LX8386/86A/86B series ICs are positive regulators designed to provide 1.5A 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 this product, the dropout voltage is fully specified as a function of load current. Dropout is guaranteed at a maximum of 1.3V (LX8386A/86B) and 1.5V (LX8386) at maximum output current, decreasing at lower load currents. On-chip trimming adjusts the reference voltage to 1% (0.8% for the 8386B) initial accuracy and 2% (1% for the 8386B) over line, load and temperature. The LX8386/86A/86B series devices are pin-compatible with earlier 3- terminal regulators, such as 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 LX8386/86A/86B series quiescent current flows into the load, increasing efficiency. This feature contrasts with PNP regulators, where up to 10% of the output current is wasted as quiescent current. The LX8386-xxI is specified over the full industrial temperature range of -25°C to +125°C and the LX8386/86A/86B-xxC is specified over the commercial range of 0°C to +125°C. s s s s s Three-Terminal Adjustable or Fixed Output s s s s s Guaranteed <1.3V Headroom at 1.5A (LX8386A/86B) s s s s s Output Current of 1.5A Minimum s s s s s Operates Down to 1V Dropout p 0.015% Line Regulation p 0.1% Load Regulation s Evaluation Board Available: Request LXE9001 EVALUATION KIT APPLICA TIONS s High Efficiency Linear Regulators s Post Regulators For Switching Power Supplies s Battery Chargers s Constant Current Regulators s ASIC & Low Voltage IC Supplies s Memory Cards s Graphics & Sound Chipsets PRODUCT HIGHLIGHT 3.3V, 1.5A REGULATOR LX8386 200 Ω 1% 1% 3.3V at 1.5A 5V OUT IN ADJ 1500µF 6MV1500GX 1500µF, 6.3V 6MV1500GX from Sanyo 121 Ω 1.5A L OW D ROPOUT P OSITIVE R EGULA TORS P RODUCTION D AT A S HEET T HE I NFINITE P OWER OF I NNOV A TION LX8386-xx/8386A-xx/8386B-xx LIN DOC #: 8386 LX8386/86A/86B-00 Adjustable LX8386/86A/86B-33 3.3V Part # Output Voltage AVAILABLE O PTIONS PER PAR T # Other voltage options may be available — Please contact factory for details.
