General Description
LX8816 General Description
The LX8816 is a dual channel positive-voltage linear regulator. This dual regulator has one fixed output coupled with an adjustable output. Each channel features low-dropout and high accuracy.
The LX8816 provides designers with a flexible power management olution, minimal printed circuit board area and shorter design cycles. Each channel can supply up to one amp independently with a regulator design optimized for system efficiency by consuming minimal ground current and directing quiescent current to the oad.
The LX8816 features on-chip rimming of the internal voltage enabling precise output voltages, typically ±1% of it's specified value, while the BiPolar output transistor has a low dropout voltage even at full output current (VDO < 1.2V typ. @ 1A).
Thermal and Short Circuit Current Prote ction are integrated on-chip and operate independently for each regulator output.
The LX8816 regulator is stable with a low-value output capacitor, typically 2.2µF on the outputs, allowing designers flexibility in external compo nent selection.
Microsemi's S-PAK package enables maximum power dissipation and ease of assembly using surface mount technology.
