uP8809 - uPI Semiconductor

uP8809 2A Ultra Low Dropout Linear Regulator

The uP8809 is an ultra low dropout linear regulator specifically designed to provide termination voltage for DDR memory system. Designed with low on-resistance NMOSFETs, this device is capable of sinking/sourcing up to 2A output current. This device works with dual supplies, a control input for the control circuitry and a power input as low as 1.0V for provi.

Features

include chip shutdown function, soft-start, on-chip thermal protection, and bi-directional current limit protection. The uP8809 is available in PSOP-8L, FSOP8L, WDFN3x3-8L packages with very low thermal resistance.
