Semtech Corporation SC900A

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. These include the ability to independently turn on any combination of the ﬁve regulators.

DESCRIPTION

Many features of the SC900A are programmable through the I2C interface. All ﬁve of the LDO output voltages are programmable in 50mV steps from 1.45V to 3.00V for LDOs A and B, and from 1.75V to 3.30V for LDOs C, D and E. 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 SC900A 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. SC900A
