LM185-1.2-N/LM285-1.2-N/LM385-1.2-N Micropower Voltage Reference Diode

Check for Samples: LM185-1.2-N, LM285-1.2-N, LM385-1.2-N

Careful design of the LM185-1.2-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.

•

±1% and 2% Initial Tolerance

Operating Current of 10μA to 20mA

1Ω Dynamic Impedance

•

Low Temperature Coefficient

Low Voltage Reference—1.235V

The extremely low power drain of the LM185-1.2-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.

2.5V Device and Adjustable Device Also

Available

•

LM185-2.5 Series and LM185 Series,

respectively

Further, the wide operating current allows it to

replace older references with a tighter tolerance part.

DESCRIPTION

The LM185-1.2-N is rated for operation over a −55°C

to 125°C temperature range while the LM285-1.2-N is

rated −40°C to 85°C and the LM385-1.2-N 0°C to

70°C. The LM185-1.2-N/LM285-1.2-N are available in

a hermetic TO package and the LM285-1.2-N/LM385-

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

package, as well as SOIC and SOT-23.

The LM185-1.2-N/LM285-1.2-N/LM385-1.2-N are

micropower 2-terminal band-gap voltage regulator

diodes. Operating over a 10μA to 20mA current

range, they feature exceptionally low dynamic

impedance and good temperature stability. On-chip

trimming is used to provide tight voltage tolerance.

Since the LM185-1.2-N band-gap reference uses only

transistors and resistors, low noise and good long

term stability result.
