Dual Channel 2.5a Low Dropout Regulator Corporation

The LX8821 is a positive-voltage linear Regulator with one fixed and one adjustable output featuring low- dropout and high accuracy. To maximize efficiency, the LX8821 accepts two supply voltage inputs for the VCONTROL and VPOWER sections. This configuration reduces power dissipation by operating the Regulator near dropout (VPWR-VOUT = VDO = 0.4V @ 2A) while providing sufficient operating headroom for the control Logic Each channel CAN supply up to 2.5A independently with a Regulator design optimized for system efficiency by consuming minimal ground current and directing quiescent current to the load The internal Voltage Reference is trimmed at wafer level, enabling precise output voltages, typically 1% of its specified value. Power sequencing Logic ensures proper startup regardless of the level of VCTRL or VPWR. The LX8821 outputs remain off while VPWR < 2.2V. Thermal and Short Circuit Current Protection are integrated on-chip and operate independently for each Regulator output. The LX8821 Regulator is stable with a wide range of output capacitance and ESR; typically 10F tantalum or ceramic on the outputs is sufficient. Microsemi uses a low profile power package with low thermal resistance and ease of assembly using surface mount technology. By Microsemi Corporation
