LP3927 Product details

Description

The LP3927 system power management IC is designed for cellular/PCS handsets as well as other portable systems that require intelligent power management.

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 rated at 100 mA. All LDO’s are optimized for low noise and high isolation. The open drain output current sink can be programmed up to 150 mA by using an external low cost resistor. A single supply, low.
