LOW POWER, BANDGAP VOLTAGE REFERENCES

GENERAL DESCRIPTION

The TC04 (1.25V output) and TC05 (2.5V output) bipo-

lar, two-terminal, bandgap voltage references offer preci-

sion performance without premium price. These devices

do not require thin-film resistors, greatly lowering manufac-

turing complexity and cost.

A 50ppm/

°C output temperature coefficient and 15µA

to 20mA operating current range make these devices at-

tractive for multimeter, data acquisition converter, and tele-

communication voltage references.
