LM385Z-1.2RP

Overview

The LM385Z-1.2RP is a precision shunt voltage reference from the LM385Z series, manufactured by onsemi. It provides a nominal output voltage of 1.235V with an initial accuracy of ±2.0%. The device operates in a wide current range from 10µA to 20mA and features low dynamic impedance and low noise. Packaged in a 3-pin TO-92 through-hole case, it is designed for stable operation over temperature. Key parameters include a load regulation of 20mV, a maximum output current of 20mA, and an operating temperature range from 0°C to +70°C.

Feature Summary

Precision bandgap voltage reference design offering strict voltage tolerance via internal trimming.
Wide dynamic operating range supports excellent regulation performance across varying load conditions.
Low power consumption characteristics suitable for extending battery life in micro-power circuits.

Applications

Portable instruments requiring precise voltage references
Battery-powered analog circuits
Power management systems

Procurement Notes

Verify the specific suffix RP against official onsemi documentation to confirm tape-and-reel packaging versus bulk bag configuration. Confirm current availability status as distribution channels may list obsolete or end-of-life variants. Ensure the ordering part number matches the required tolerance and package style specified in the final design.

Selection Notes

Select this component when a fixed 1.235V reference is needed in a through-hole TO-92 package. Consider the ±2.0% initial accuracy and 0°C to +70°C commercial temperature range. Evaluate the 10µA to 20mA operating current window to ensure compatibility with the circuit's bias requirements and power constraints.

Part Context

This part belongs to the LM385Z family of micro-power shunt regulators. These devices are bipolar, two-terminal bandgap references known for low cost and high precision. The LM385Z series is widely used in applications where stable voltage referencing is critical but power consumption must remain minimal.
