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

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the package designation matches the required SC-74A/SOT-753 footprint for PCB layout compatibility. Ensure the fixed 3.3 V output aligns with system voltage requirements before integration.

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

Select this component when a fixed 3.3 V rail is needed with minimal static power draw. The 50 mA output capability suits low-power digital logic and sensor interfaces. Consider the 16 V input tolerance for systems with higher supply voltages. The wide operating temperature range ensures reliability in harsh environments.

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

This part belongs to the TPS77x family of low-quiescent-current LDO regulators. It shares architectural similarities with other members like the TPS77018 and TPS77050, differing primarily in output voltage settings. The DBVT package variant offers 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 include TPS77033DBVR and TPS77033DBVRE4. Verify pinout compatibility and electrical specifications such as PSRR and dropout voltage when cross-referencing with alternative LDO models from Texas Instruments or other manufacturers.
