TLV743105PDBVR

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

The TLV743105PDBVR is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It provides a fixed output voltage of 1.05 V with a maximum output current of 300 mA. The device operates within an input voltage range of 1.4 V to 5.5 V and features a typical dropout voltage of 122 mV at full load. It incorporates foldback overcurrent protection and maintains stability with only a 1-μF ceramic output capacitor. The regulator is housed in a SOT-23-5 package and supports operation across a temperature range of -40°C to +125°C.

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

Verify the specific output voltage tolerance and package marking against the official Texas Instruments datasheet for the TLV743105PDBVR variant. Confirm that the supplier provides traceable documentation matching the manufacturer's specifications. Ensure compatibility with your board's thermal design and input voltage constraints before finalizing procurement decisions.

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

Select this component when a precise 1.05 V output is required with high efficiency in a compact form factor. It is suitable for designs where minimizing external capacitance and maintaining low quiescent current are priorities. Consider the 300 mA current limit and dropout characteristics relative to your input voltage headroom and load profile.

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

This part belongs to the TLV743P series of low-dropout regulators from Texas Instruments. The series is characterized by its ability to operate with small ceramic capacitors and its robust protection features. The PDBVR suffix indicates the SOT-23-5 package and tape-and-reel packaging format used for automated assembly processes.

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

Direct substitutes include other parts from the TLV743P family with compatible output voltages and packages, such as the TLV74310PDBVR (1.0 V) or TLV74311PDBVR (1.1 V), provided the voltage difference is acceptable for the application circuit.
