Overview
The CAT3200ZI-T3 is a low noise regulated charge pump DC-DC converter manufactured by onsemi. It functions as an adjustable voltage regulator within the PMIC category, specifically designed for DC-DC switching applications. The device is housed in an 8-MSOP package and supports surface mount installation. It provides an output current capability of 100mA. The component is classified as obsolete and is no longer in active manufacturing.
Feature Summary
- Regulated charge pump topology for DC-DC conversion
- Adjustable output voltage regulation
- Low noise performance characteristics
Applications
- Portable electronic devices requiring efficient step-up or level-shifting power
- Systems utilizing low noise power supplies for sensitive analog circuits
- Battery-powered applications needing compact DC-DC regulation
Procurement Notes
This component is officially listed as obsolete by onsemi and is no longer manufactured. Availability is restricted to existing stock or secondary market sources. Verification of authenticity and condition is critical when sourcing from non-direct channels. Ensure compatibility with legacy designs before procurement.
Selection Notes
Engineers should consider this part only for maintenance of existing hardware where redesign is not feasible. Due to its obsolete status, alternative components with similar charge pump functionality and 100mA output current in an 8-MSOP package must be evaluated for new designs. Verify pinout and electrical specifications against potential replacements.
Part Context
The CAT3200ZI-T3 belongs to onsemi's portfolio of power management integrated circuits (PMIC). It falls under the subcategory of voltage regulators, specifically DC-DC switching regulators. The 'T3' suffix typically denotes tape and reel packaging, while 'ZI' indicates the MSOP-8 package variant. This specific part number represents a discontinued product line.
Replacement Considerations
As the CAT3200ZI-T3 is obsolete, direct substitutes are not guaranteed by the manufacturer. Engineers must identify third-party equivalents that match the 8-MSOP footprint, 100mA current rating, and adjustable charge pump architecture. Cross-referencing datasheets for compatible pinouts and electrical parameters is essential.
