3-5TELCOM SEMICONDUCTOR, INC. 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.
