TPS73512DRBR

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

The TPS73512DRBR is a single-output low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It provides a fixed output voltage of 1.2 V with a maximum continuous output current of 500 mA. The device operates within an input voltage range up to 6.5 V and features a typical quiescent current of 45 uA. Key electrical parameters include a maximum dropout voltage of 500 mV at full load, a line regulation of 0.02 %/V, and a load regulation of 0.005 %/mA. Power supply rejection ratio (PSRR) is typically 22 dB. The component is housed in an 8-SON package and supports operation temperatures from -40°C to +125°C.

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

Verify the specific suffix DRBR corresponds to the 8-SON surface-mount package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) requirements for your assembly process. Ensure the fixed 1.2 V output matches your system design needs, as adjustable variants exist within the same family.

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

Select this part when a fixed 1.2 V rail is required with moderate current demands up to 500 mA. Consider the 45 uA quiescent current for standby efficiency. Compare against other TPS735 variants if different output voltages or adjustable outputs are needed. Verify input voltage headroom against the specified dropout characteristics to ensure regulation stability under all load conditions.
