LM385PW-1-2 TI Voltage Reference | 8-TSSOP | 1.235V, 20ppm/°C

Product Overview

The LM385PW-1-2 from Texas Instruments is a precision micropower voltage reference diode offering a fixed 1.235V output. Housed in an 8-TSSOP package, it is designed for low-power and portable applications requiring high accuracy and stability over temperature and time. With an initial tolerance of ±1.5% and a temperature coefficient as low as 20ppm/°C, it provides a reliable reference for data converters, power supplies, and measurement systems.
