NCP1835BMNR2

Overview

The NCP1835BMNR2 is a low-dropout (LDO) voltage regulator manufactured by onsemi, designed for high-performance power management applications. It features a fixed output voltage of 3.3 V and supports an output current of 250 mA. The device incorporates ultra-high Power Supply Rejection Ratio (PSRR) characteristics to minimize noise coupling from the input supply line, ensuring clean power delivery to sensitive downstream components. It operates within a specified temperature range suitable for industrial and commercial environments.

Feature Summary

• Ultra-low output noise characteristic
• Fixed 3.3 V output voltage configuration
• Compact SOT-23-5 surface-mount package

Applications

• Portable electronic devices requiring stable 3.3 V rails
• Embedded systems with noise-sensitive analog circuits
• Industrial control modules needing reliable LDO regulation

Procurement Notes

Verify the complete ordering part number against official onsemi documentation to ensure correct suffix alignment. Confirm that the specific variant matches the required thermal and electrical specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.3 V output is required with stringent noise rejection criteria. The 250 mA current capability suits moderate load applications. Ensure the input voltage range accommodates the system's supply variations while maintaining adequate dropout voltage margins for stable regulation under all operating conditions.

Part Context

This LDO belongs to onsemi's portfolio of low-noise regulators optimized for demanding power integrity requirements. It complements other series like the NCP163 and NCP114, offering distinct trade-offs between current capacity, noise performance, and PSRR levels for diverse system architectures.

Replacement Considerations

Cross-reference with NCP163AFCS280T2G for similar ultra-high PSRR and low noise profiles in 250 mA applications. Verify pin compatibility and thermal dissipation requirements when substituting with alternative LDOs from different manufacturers or series.
