Overview
The LM385BZ-1.2RAG is a micropower two-terminal bandgap voltage regulator diode manufactured by onsemi. It provides a nominal reference voltage of 1.235V with an initial tolerance 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 operation between 0°C and +70°C.
Feature Summary
- Micropower two-terminal bandgap voltage regulation
- Tight voltage tolerance via on-chip trimming
- Low dynamic impedance and low noise characteristics
- Wide operating current range for flexible supply designs
Applications
- Portable instrumentation circuits
- Battery-powered analog circuitry
- Precision voltage references
- Regulator biasing networks
Procurement Notes
Verify the specific suffix 'RAG' against official onsemi documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the ordering part number matches the exact tolerance grade and package variant required for your design. Cross-reference datasheets for any regional manufacturing variations or compliance updates.
Selection Notes
Select this component when a fixed 1.235V reference is needed with high precision in a cost-effective through-hole package. The ±1.0% tolerance suits applications requiring tighter accuracy than standard grades. Consider the TO-92 form factor for prototyping or space-constrained PCB layouts where surface-mount alternatives are not preferred.
Part Context
This part belongs to the LM385 series of micropower voltage references. It shares core electrical characteristics with other variants like the LM385Z-1.2 but offers improved initial tolerance accuracy. The series is widely used in general-purpose analog applications requiring stable, low-noise voltage references without complex external components.
Replacement Considerations
LM385BZ-1.2/NOPB: Texas Instruments equivalent with identical electrical specifications and pinout. LM385Z-1.2G: ON Semiconductor variant with slightly looser ±2.0% tolerance but compatible package and function.
