LP3927 Features

* an extremely low dropout voltage of 100 mV (typ) at maximum output current. LDO1 and LDO2 are powered on and off by either the KYBD or the VEXT pin. LDO3, LDO4 and LDO5 each have its independent enable pin. LDO1 and LDO4 are rated at 150 mA each, LDO2 and LDO5 are rated at 200 mA each and LDO3 is ra

LP3927 General Description

The LP3927 system power management IC is designed for cellular/PCS handsets as well as other portable systems that require intelligent power management. Each device contains five low-dropout linear regulators (LDO’s), a reset timer, a power-up control logic, a general-purpose open drain output that .
