uP8809

2A Ultra Low Dropout Linear Regulator

Features

General Description

The uP8809 is an ultra low dropout linear regulator Generate Termination Voltage for DDR Memory

specifically designed to provide termination voltage forDDR

memory system. Designed with low on-resistance

NMOSFETs, this device is capable of sinking/sourcing up

to 2A output current.

Interface

Output Voltage Traces Reference Input

Capable of Sinking/Sourcing 2A

Integrated Low R_DS(ON)MOSFETs

Excellent Line and Load Regulation

Low External Part Count

This device works with dual supplies, a control input for

the control circuitry and a power input as low as 1.0V for

providing current to output. The output voltage is tightly

regulated to track reference voltage input within 20mV

variation with fast to line/load transient.

Bidirectional Current Limit Protection

On-Chip Thermal Protection

Support Pure MLCC

Other features include chip shutdown function, soft-start,

on-chip thermal protection, and bi-directional current limit

protection. The uP8809 is available in PSOP-8L, FSOP-

8L, WDFN3x3-8Lpackages with very low thermal resistance.

RoHS Compliant and Halogen Free
