LM10502TLE/NOPB

Power Management - Specialized Overview

The LM10502TLE/NOPB is a specialized power management integrated circuit (PMIC) manufactured by Texas Instruments. It integrates two synchronous step-down DC/DC converters and one low-dropout linear regulator within a single package. The device operates with an input voltage range of 3 V to 5.5 V and features a quiescent current of 70 uA. The output currents are rated at 250 mA for the regulators. It utilizes a DSBGA-25 surface-mount package and supports operation temperatures from -30°C to +125°C.

Power Management - Specialized Feature Summary

• Integrates dual synchronous buck converters and a single LDO in a compact footprint
• Optimized for low standby power consumption with minimal quiescent current draw
• Designed specifically for complex mobile system power sequencing requirements

Power Management - Specialized Applications

• Mobile phone mainboard power distribution
• Smartphone application processor core voltage regulation
• Portable multimedia devices requiring multiple supply rails

Power Management - Specialized Procurement Notes

Verify component authenticity through authorized channels, as this part is marked NRND. Confirm package integrity upon receipt due to the small DSBGA form factor. Ensure storage conditions meet manufacturer specifications to prevent moisture sensitivity issues before reflow soldering.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring three distinct regulated outputs from a single 3V to 5.5V rail. Consider the thermal performance of the DSBGA-25 package under maximum load conditions. Evaluate the specific current demands of the target loads against the 250 mA rating to ensure adequate headroom.

Power Management - Specialized Part Context

This unit belongs to the LM10502 series, which focuses on highly integrated power solutions for portable electronics. It replaces discrete regulator designs to save board space. The NOPB suffix indicates lead-free and RoHS compliance, aligning with modern environmental standards for consumer electronics manufacturing.

Power Management - Specialized Replacement Considerations

Consult official substitution lists for updated alternatives. Verify pin compatibility and electrical parameters if considering cross-series replacements.
