TPS76950DBVT

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TPS76950DBVT is a fixed-output low-dropout linear regulator manufactured by Texas Instruments, designed for ultra-low-power applications. It provides a stable 5V output with a maximum continuous current of 100mA. The device supports an input voltage range from 2.7V to 10V and operates within a temperature range of -40°C to +125°C. Key electrical characteristics include a typical quiescent current of 28µA and a maximum dropout voltage of 85mV at full load. It features high power supply rejection ratio (PSRR) and includes comprehensive protection mechanisms such as overcurrent, thermal shutdown, and reverse current protection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Ultra-low quiescent current design minimizes power consumption in battery-operated systems.
• Integrated reverse current protection prevents backflow when the input voltage drops below the output voltage.
• Robust protection suite includes overcurrent limiting, thermal shutdown, and undervoltage lockout for reliable operation.

• Medical instrumentation with strict power constraints

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'DBVT' corresponds to the SOT-23-5 package variant. Confirm that the 100mA output current meets system requirements, as this differs from higher-current LDOs. Ensure compatibility with the 10V maximum input voltage limit. Check for automotive qualification if used in vehicle environments, as standard versions may differ from Q1 variants.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when ultra-low static current is critical compared to standard LDOs. The 100mA output capability suits low-power microcontrollers and sensors. Consider the 10V input limit; higher input voltages require alternative regulators. The SOT-23-5 package offers space efficiency for compact designs. Verify thermal performance under expected load conditions.
