TPS75218QPWPRQ1

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

The TPS75218QPWPRQ1 is a fixed-output low-dropout (LDO) voltage regulator from the TPS752 series, designed for automotive applications. It provides a fixed 1.8 V output with a maximum continuous current of 2 A. The device operates within an input voltage range of 2.7 V to 5.5 V and features a typical dropout voltage of 210 mV at full load. It maintains a quiescent current of 125 µA and ensures voltage regulation accuracy of ±2%. The component is housed in a 20-pin HTSSOP package and supports operation across an extended temperature range from -40°C to +125°C.

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

Verify that the ordering suffix matches the required tape-and-reel packaging configuration. Confirm the specific output voltage variant corresponds to the design requirement. Ensure the component meets the necessary AEC-Q100 qualification level for the target automotive application environment.

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

Select this regulator when a fixed 1.8 V rail is required with high current capacity up to 2 A. Consider the fast transient response feature if the load profile involves significant dynamic variations. Verify that the input voltage remains within the specified 2.7 V to 5.5 V window to ensure proper regulation and thermal performance.

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

This component belongs to the TPS752 family of high-performance LDOs optimized for automotive use. It shares the same core architecture as the non-qualified TPS75218 but includes enhanced testing and documentation to meet automotive quality standards. The part is distinct from adjustable variants like the TPS75201.

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

The TPS75218QPWP serves as a non-automotive qualified alternative. For direct replacement, verify that the package dimensions and pinout are identical. Note that the non-Q1 version may lack the specific automotive reliability certifications required for safety-critical systems.
