Overview
LIN D O C # : 8386 LX8386-xx/8386A-xx/8386B-xx 1 .
5 A LOW DR O P O U T P OSITIVE R E G U L AT O R S T H E I N F I N I T E P O W E R O F I N N O VA T I O N P R O D U C T I O N D A T A S H E E T DESCRIPTION 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 3terminal 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.
