At the designed maximum load current, the LX8117 series dropout voltage is guaranteed to be 1.
2V or lower at 0.
8A (LX8117A 1.
3V @ 1A).
The dropout voltage decreases with load current.
An adjustable output voltage version of the LX8117/17A/17B is available, as well as versions with fixed outputs of 2.
5V, 2.
85V, 3.
3V and 5V.
The 2.
85V version is specifically designed for use as a component of active termination networks for the SCSI bus.
On-chip trimming of the internal voltage reference allows specification of the initial output voltage to within ±1% of its nominal value.
The output current-limit point is also trimmed, which helps to minimize stress on both the regulator and the system power source when they are operated under short-circuit conditions.
The regulator's internal circuitry will operate at input-to-output differential voltages down to 1V.
Most regulator circuit designs include output capacitors with values in the range of tens to hundreds of microfarads or more.
The LX8117/17A/17B typically requires at least 10µF of output capacitance for stable operation.
PNP-type regulators can waste current equal to as much as 10 percent of their output as a quiescent current which flows directly to ground, bypassing the load.
Quiescent current from the LX8117/17A/ 17B flows through the load, increasing power-use efficiency and allowing cooler operation.
The LX8117 is available in low-profile plastic SOT-223 and D-Pak packages for applications where space is at a premium.
The LX8117 is also available in a plastic TO-263 package for instances when the thermal resistance from the circuit die to the environment must be minimized.
