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 15
μ
A
to 20mA operating current range make these devices at-
tractive for multimeter, data acquisition converter, and tele-
communication voltage references.
