2.5V Reference

The LM136-2.5 is a general purpose shunt regulator diode

designed to operate over a wide current range while

maintaining good stability with time and temperature. The

third terminal allows either the temperature coefficient to

be minimized or the reference voltage to be adjusted

without changing the temperature coefficient. Because it

operates as a shunt regulator it can be used equally well as

a positive or negative reference.

The LM136-2.5 is available with initial tolerances as low as

1% in either a TO-46 metal can for hermetic requirements

or a low cost TO-92 plastic package.

Linear’s advanced design, test and process techniques

have optimized the LM136-2.5 to achieve superior perfor-

mance and reliability over previous designs. For more

demanding precision reference applications requiring very

low initial tolerance and temperature coefficients, consult

the LT1009 data sheet. A typical 2.5V reference with trim

is shown below.
