TPS7A2031PDBVR

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

The TPS7A2031PDBVR is a fixed-output low-dropout (LDO) voltage regulator from Texas Instruments, housed in an SOT-23-5 package. It provides a fixed output voltage of 3.1 V with a maximum continuous output current of 300 mA. The device operates within an input voltage range of 1.6 V to 6 V and maintains a typical quiescent current of 6.5 uA. Key performance metrics include a maximum dropout voltage of 145 mV at full load, a line regulation of 0.03 %/V, and a load regulation of 19 mV. It offers a typical power supply rejection ratio (PSRR) of 65 dB and functions reliably across an operating temperature range of -40°C to +125°C.

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

Verify the complete part number including the suffix to ensure correct output voltage and packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet revisions to validate electrical characteristics against your specific design requirements. Ensure thermal management strategies align with the specified operating temperature range for reliable long-term performance.

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

Select this component when a fixed 3.1 V output is required with minimal noise interference. Consider the 300 mA current limit for load capacity planning. Evaluate the 6.5 uA quiescent current impact on overall battery life. Verify that the input voltage range accommodates your source supply variations. Compare PSRR specifications against other LDOs if high-frequency noise suppression is critical for the application.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This device belongs to the TPS7A20 series of ultra-low-noise LDO regulators from Texas Instruments. The series shares common architectural features such as low quiescent current and high PSRR, differentiated primarily by fixed output voltage options. The PDBVR suffix indicates surface-mount packaging in a small form factor suitable for space-constrained designs within the broader PMIC portfolio.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes within the same family include TPS7A2025PDBVR (2.5 V), TPS7A2030PDBVRG4 (3.0 V), and TPS7A2036PDBVR (3.6 V). These alternatives share identical pinouts and electrical characteristics except for the fixed output voltage. Ensure the replacement voltage matches the target circuit requirement before substitution.
