5V Bandgap Reference

FEATURES

DESCRIPTIO

The LT^®1029 is a 5V bandgap reference intended for use

in the shunt or “Zener” mode, allowing it to be used as

either a positive or negative reference. The output is

pretrimmedto±0.2%accuracywith20ppm/°Cmaximum

temperature drift. A trim pin allows additional output

adjustment for even more precise output voltage.

■

0.2% Output Tolerance

■

0.6Ω Shunt Impedance

■

700µA to 10mA Operating Current

■

Pin Compatible with LM136-5

■

20ppm/°C Max Drift

■

Output Voltage Trim does not Affect Drift

■

Can be Used as Positive or Negative Reference

OperatingcurrentrangefortheLT1029is700µAto10mA.

Extremely low dynamic impedance allows excellent

output regulation even with fluctuating operating current.

APPLICATIO S

The LT1029 will replace an LM136-5 or LM336-5 and

simplify circuits using the “minimum temperature coeffi-

cient” trim network. The LT1029 does not require this

specialnetworktomeetitstemperaturedriftspecification;

these application network components are simply

removed. If output trimming is required for initial

accuracy, the diodes in the trim network should be

replaced with jumpers.
