LM185-2.5-N/LM285-2.5-N/LM385-2.5-N Micropower Voltage Reference Diode

Check for Samples: LM185-2.5-N, LM285-2.5-N, LM385-2.5-N

Careful design of the LM185-2.5-N has made the

FEATURES

device exceptionally tolerant of capacitive loading,

making it easy to use in almost any reference

application. The wide dynamic operating range allows

its use with widely varying supplies with excellent

regulation.

•

±20 mV (±0.8%) max. Initial Tolerance (A

Grade)

•

Operating Current of 20 μA to 20 mA

0.6Ω Dynamic Impedance (A Grade)

Low Temperature Coefficient

The extremely low power drain of the LM185-2.5-N

makes it useful for micropower circuitry. This voltage

reference can be used to make portable meters,

regulators or general purpose analog circuitry with

battery life approaching shelf life. Further, the wide

operating current allows it to replace older references

with a tighter tolerance part. For applications requiring

1.2V see LM185-1.2.

Low Voltage Reference—2.5V

1.2V Device and Adjustable Device Also

Available—LM185-1.2 Series and LM185

Series, respectively

DESCRIPTION

The LM185-2.5-N/LM285-2.5-N/LM385-2.5-N are

micropower 2-terminal band-gap voltage regulator

diodes. Operating over a 20 μA to 20 mA current

range, they feature exceptionally low dynamic

impedance and good temperature stability. On-chip

trimming is used to provide tight voltage tolerance.

Since the LM-185-2.5-N band-gap reference uses

only transistors and resistors, low noise and good

long term stability result.

The LM185-2.5-N is rated for operation over a −55°C

to 125°C temperature range while the LM285-2.5-N is

rated −40°C to 85°C and the LM385-2.5-N 0°C to

70°C. The LM185-2.5-N/LM285-2.5-N are available in

a hermetic TO package and the LM285-2.5-N/LM385-

2.5-N are also available in a low-cost TO-92 molded

package, as well as SOIC and SOT-23. The LM185-

2.5-N is also available in a hermetic leadless chip

carrier package.
