LM385Z-1.2RPG

Overview

The LM385Z-1.2RPG is a shunt voltage reference IC manufactured by onsemi, housed in a TO-92-3 (TO-226AA) through-hole package. It provides a fixed nominal output voltage of 1.235V with a tolerance range of -2.4% to +2.01%. The device operates within a cathode current range from 20 µA to 20 mA and features a standard temperature coefficient of 80 ppm/°C. Noise performance is specified at 60 µVrms over the 10 Hz to 10 kHz frequency band. It functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

Provides stable precision voltage reference via shunt topology
Operates effectively across a wide dynamic current range
Maintains low noise characteristics for sensitive analog circuits

Applications

Portable instrumentation requiring low power consumption
Battery-powered measurement devices
Analog circuit biasing and regulation

Procurement Notes

Verify component status as this specific part number may be subject to end-of-life notices or discontinuation. Confirm that the TO-92-3 package and electrical specifications align with design requirements before procurement. Check for RoHS compliance status and ensure availability of alternative sources if supply chain constraints exist.

Selection Notes

Select this component when a fixed 1.235V reference is required in a through-hole configuration. Consider the 80 ppm/°C temperature coefficient and 60 µVrms noise level against application needs. Ensure the operating environment stays within the 0°C to 70°C commercial temperature range and that current limits between 20 µA and 20 mA are respected.

Part Context

This device belongs to the LM385 series of micropower bandgap voltage references designed for applications demanding stability and low power. The series utilizes internal trimming for strict voltage tolerances and offers low dynamic impedance. It is suitable for portable equipment and power management systems where extended battery life and precise voltage regulation are critical.
