LT1009CDR Description

Short technical summary and product information.

The LT1009CDR is a precision-trimmed 2.5-V shunt voltage regulator from Texas Instruments, designed for applications requiring stable voltage references. It features a low dynamic impedance and a wide operating current range, making it versatile for various circuit designs.

Key electrical specifications include a fixed 2.5-V output voltage with a maximum initial accuracy of 0.2%. The device operates over a temperature range of -40°C to 85°C, with a maximum temperature coefficient of 25 ppm/°C, ensuring reliable performance across different environmental conditions. The minimum regulation current is 400 µA, and the maximum output current to regulation current ratio is 10 mA.

Available in TO-92 (LP), TSSOP (PW), and SOIC (D) packages, the LT1009CDR can be used in applications such as 5-V system references, analog-to-digital converter (ADC) and digital-to-analog converter (DAC) references, and power-supply monitors. It can also serve as a direct replacement for the LM136-2.5, simplifying design and reducing component count by eliminating the need for external trim networks.
