• Shutdown pin enables low quiescent current standby mode
• Built-in thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered equipment
• Point-of-load regulation for digital signal processors
• Embedded systems with single-cell lithium-ion inputs
• Industrial control modules requiring compact power solutions

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'YSDE' against the manufacturer's official datasheet to confirm the specific tape-and-reel packaging configuration and temperature grade. Ensure compatibility with standard WSON-6 footprint dimensions during PCB layout. Cross-reference the part number with the latest Texas Instruments ordering information to avoid obsolete or alternate revision discrepancies.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when input voltages are limited to 5.5 V maximum and space constraints require a 3 MHz switching frequency. Compare against the LMR10515XSD variant if a lower 1.6 MHz frequency is preferred for reduced EMI. Consider the WSON-6 package thermal performance relative to the expected load current and ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LMR10515 family of SIMPLE SWITCHER regulators. It shares core architecture with variants like LMR10515YMF and LMR10515XSD but differs in package type (WSON-6 vs SOT-23-5) and switching frequency options. The family targets low-voltage, high-current applications requiring minimal external component count.
