National Semiconductor Introduces Tiny System Power Management IC with Digital Control for Portable Systems

February 15, 2006 - National Semiconductor Corporation (NYSE:NSM) today introduced a system power management IC with digitally controlled sequencing.  Packaged in a very small leadless leadframe package (LLP®), the LP3927 is well-suited for cellular and PCS handsets as well as other portable systems that require intelligent power management.

The LP3927 contains five low-dropout linear regulators (LDOs), a reset timer, power-up control logic, a general-purpose open drain output that can be used to light LEDs and a CMOS rail-to-rail input/output operational amplifier.  Each LDO features an extremely low dropout voltage of 100 mV at maximum load current.  The maximum load current supported by the LDOs ranges from 100 mA to 200 mA. All the linear regulators are optimized for use with sensitive analog and RF loads that need low noise and high power supply rejection.

Key features for the LP3927 include:
