TO-92 Plastic Package
8-Pin Plastic Narrow Body SOIC Package
The TC04 (1.25V output) and TC05 (2.5V output) bipolar, two-terminal, bandgap voltage references offer precision performance without premium price. These devices
do not require thin-film resistors, greatly lowering manufacturing complexity and cost.
A 50ppm/°C output temperature coefficient and 15µA
to 20mA operating current range make these devices attractive for multimeter, data acquisition converter, and telecommunication voltage references.
