LM385BZ-1.2

Overview

The LM385BZ-1.2 is a micropower two-terminal bandgap voltage reference diode manufactured by onsemi. It provides a nominal output voltage of 1.235 V with an initial tolerance grade of 1.0%. The device operates within a wide current range from 10 µA to 20 mA, featuring low dynamic impedance and low noise for stable performance over time and temperature. It is housed in a TO-92 (TO-226AA) plastic package designed for through-hole mounting. The component is rated for commercial temperature operation from 0°C to +70°C.

Feature Summary

Micropower two-terminal bandgap voltage regulation
Wide operating current range from 10 µA to 20 mA
Low dynamic impedance and low noise characteristics
Tight voltage tolerances achieved via on-chip trimming

Applications

Portable instrumentation circuits
Battery-powered analog circuitry
Voltage regulators requiring extended battery life
Precision current sources

Procurement Notes

Verify the specific manufacturer origin, as the LM385 series was originally developed by Motorola and later acquired by onsemi. Confirm that the ordering suffix matches the required tolerance grade and package type. Ensure compliance with relevant environmental standards such as RoHS if applicable to the specific production batch. Cross-reference datasheets from both Texas Instruments and onsemi for pinout consistency.

Selection Notes

Select this component when a stable 1.235 V reference is needed in space-constrained designs using through-hole packages. The wide current range allows flexibility in biasing resistor selection. Consider the commercial temperature range limits for high-temperature environments. Compare against LM285 variants if wider industrial temperature ranges are required.

Part Context

The LM385 series belongs to a family of micropower shunt voltage references widely used in analog electronics. The 'B' suffix typically denotes a tighter initial voltage tolerance compared to standard grades. This specific model represents the 1.235 V version packaged in the legacy TO-92 form factor, suitable for general-purpose voltage referencing tasks.
