MIC5166

3A High-Speed Low V_INDDR Terminator

General Description

Features

The MIC5166 is a 3A, high-speed, linear, low V_IN,double

data rate (DDR), memory terminator power supply. The

part is small and requires small output capacitors making it

a tiny overall solution. This allows it to be conveniently

placed close to the DDR memory, minimizing circuit board

layout inductance which may cause excessive voltage

ripple at the DDR memory.

• Operating voltage range:

•

V_DDQSupply: 0.9V to 3.6V

Bias Supply: 2.5V to 5.5V

• High bandwidth – very fast transient response

• Stable with two 10µF ceramic output capacitors

• Two 10µF output capacitors used in most applications

• High output voltage accuracy:

The MIC5166 contains a precision voltage divider network

in order to take in the V_DDQvoltage as a reference voltage

and conveniently output the terminator voltage (V_TT) at one

half of the V_DDQinput voltage.

•

0.015% line regulation

1.5% load regulation

• Logic level enable input

The MIC5166 is capable of sinking and sourcing up to 3A.

It is stable with only two 10µF ceramic output capacitors.

The part is available in a small 3mm × 3mm MLF^®

thermally-enhanced package.

• Power Good (PG)

• Thermally-enhanced 3mm × 3mm MLF^®

• Junction temperature range –40°C to +125°C

The MIC5166 has a high-side NMOS output stage offering

very-low output impedance, and very-high bandwidth. The

NMOS output stage offers a unique ability to respond very

quickly to sudden load changes such as is required for

DDR memory termination power supply applications.
