Semtech Corporation SC900
The SC900 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. These include the ability to indepenwww.DataSheet4U.com dently turn on any combination of the five regulators.| Part No. | SC900 |

DESCRIPTION
Many features of the SC900 are programmable through the I2C interface. All five of the LDO output voltages are programmable in 50mV steps from 1.45V to 3.00V. Each LDO can have an active shutdown or nonactive shutdown program option through the interface. There is also a reset monitor flag that is associated with LDOA. In addition, the device has a separate programmable power-good monitor flag that activates when one or more LDOs go out of regulation. The SC900 offers significant quiescent current and space savings to the system designer by sharing reference and biasing among five LDOs. The small and thermally efficient 20-lead MLPQ package make it ideal for use in portable products where minimizing layout area is critical. SC900FEATURES
