TPS75003RHLT

Power Management - Specialized Overview

The TPS75003RHLT is a specialized Power Management IC (PMIC) from Texas Instruments, designed for processor power management applications. It integrates three independent power supplies within a single package: one Low Dropout Regulator (LDO) and two Buck converters. The device operates with an input voltage range of 2.2 V to 6.5 V. The LDO output provides up to 300 mA, while the Buck converters deliver up to 3 A each. It features a low operating supply current of 150 µA and supports adjustable output voltages ranging from 1 V to 6.5 V. The component is housed in a 20-pin VQFN package measuring 3.65 mm by 4.65 mm.

Power Management - Specialized Feature Summary

• Integrates three independent power rails combining one LDO and two Buck regulators for compact system design
• Supports wide input voltage range suitable for battery-powered and regulated bus applications
• Optimized for low quiescent current consumption to extend battery life in portable devices

Power Management - Specialized Applications

• Processor power management systems requiring multiple voltage domains
• Portable electronic devices needing efficient multi-rail power distribution
• Embedded systems utilizing mixed LDO and switching regulator topologies

Power Management - Specialized Procurement Notes

Verify the specific suffix RHLT against official Texas Instruments documentation to confirm the reel quantity and tape specifications. Ensure compatibility with your assembly equipment regarding the VQFN-20 package dimensions. Cross-reference the datasheet revision history to validate electrical characteristics and pinout assignments before finalizing procurement orders.

Power Management - Specialized Selection Notes

Select this component when a single IC solution is required to generate three distinct power rails efficiently. It is appropriate for designs where board space is limited and high current delivery from buck converters is necessary alongside a clean LDO rail. Consider the thermal performance requirements given the high current capabilities of the integrated buck stages.

Power Management - Specialized Part Context

This part belongs to the TPS75003 series of specialized PMICs from Texas Instruments. The series is engineered to simplify power architecture for complex processors by consolidating multiple regulation functions into a single footprint. The RHLT suffix indicates a specific packaging variant within this family, typically denoting the reel configuration for surface-mount assembly.

Power Management - Specialized Replacement Considerations

Consult the TPS75003EVM-092 evaluation module documentation for reference designs. Verify if other suffixes within the TPS75003 family offer identical electrical performance with different packaging options. No direct cross-manufacturer substitutes are confirmed in public data.
