SC900AMLTRT 数据手册 ( 数据表 ) - Semtech Corporation

Description
The SC900A is a highly integrated power management device for low power portable applications. The device contains five adjustable low-dropout linear regulators (LDOs) with CMOS pass-devices as well as a band-gap reference, I2C interface, and DACs to control the output voltages.

FEATUREs
◆ Five LDO regulators in one package
◆ I2C interface with multiple device capability
◆ Independent I2C enable/disable of LDOs
◆ Independent I2C control of output voltages
◆ Low thermal impedance of 40°C per watt
◆ 150mV dropout at 150mA
◆ Input range from 2.7V to 5.5V
◆ Programmable power good flag
◆ Minimal number of external components
◆ Over temperature protection
◆ Small 4mm x 4mm 20-lead MLPQ package
◆ Small input/output filter capacitors
◆ Programmable VOUT range -
    1.45V to 3.00V for LDOs A and B
    1.75V to 3.30V for LDOs C, D and E

APPLICATIONs
◆ Palmtop/Laptop computers
◆ Personal Digital Assistants
◆ Cellular telephones
◆ Battery-powered equipment
◆ High efficiency linear power supplies
