MCZ33998EGR2

Overview

The MCZ33998EGR2 is a triple-output voltage regulator manufactured by NXP USA Inc., housed in a 24-SOIC package. It integrates one charge pump and two linear regulators (LDOs). The device operates within an input voltage range of 6V to 26.5V and supports a switching frequency of 750kHz. Output specifications include a 5V rail capable of delivering 1.4A. The component functions across an extended temperature range from -40°C to 125°C.

Feature Summary

• Integrates three distinct output channels combining charge pump and linear regulation topologies
• Includes internal sequencer function for controlled power-up and power-down sequences
• Linear outputs designed for low ripple and noise performance

Applications

• Power management for automotive electronic control units
• Voltage regulation in industrial embedded systems
• Power supply stages for microcontroller-based applications requiring multiple rails

Procurement Notes

Verify product status carefully as this specific part number is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing board designs before procurement, as end-of-life components may have limited long-term supply stability.

Selection Notes

Select this component when a single IC solution is required to generate three separate voltage rails efficiently. The combination of charge pump and LDO outputs reduces bill of materials count compared to discrete solutions. Consider the 24-SOIC package constraints and thermal requirements for the intended operating environment.

Part Context

This device belongs to NXP's PMIC portfolio designed for robust power management in demanding environments. It consolidates multiple regulator functions into a compact footprint, simplifying PCB layout and reducing component count for systems requiring isolated or regulated supplies from a single input source.

Replacement Considerations

As the product status is obsolete, direct substitutes must be sourced from alternative manufacturers or newer NXP revisions. Verify pin-to-pin compatibility and electrical parameter equivalence before integrating any replacement part into the design.
