LX8819

The LX8819 is a dual channel positive-voltage linear regulator. This dual regulator has one fixed output coupled with an adjustable output. Each channel features a low dropout and a high accuracy.

The LX8819 provides designers with a flexible power management solution, 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 while directing quiescent current to the load.

The LX8819 features on-chip trimming of the internal voltage reference enabling precise output Voltages (typically ±1% of its specified value) while the Bipolar output transistor has a low dropout voltage even at full output current (VDO < 1.25V typical @ 1A).Thermal and Short Circuit Current Protection are integrated on-chip and operate independently for each of the regulator output.

The LX8819 regulator is stable with a low-value output capacitor (typically 2.2F on the outputs) allowing the designers flexibility in external component selection.Microsemi's S-PAK and D-PAK power packages enable maximum power dissipation and ease of assembly using surface mount technology.
