TPS7A1128PDRVT

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

The TPS7A1128PDRVT is a fixed-output low-dropout (LDO) voltage regulator from the Texas Instruments TPS7A11 series. It provides a fixed output voltage of 2.8 V with a maximum continuous output current of 500 mA. The device operates within an input voltage range of 0.75 V to 3.3 V and maintains an ultra-low quiescent current of 1.6 µA. Key electrical characteristics include a typical dropout voltage of 130 mV, a line regulation of 0.001 %/V, and a load regulation of 0.5 %/A. It features a typical power supply rejection ratio (PSRR) of 35 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 specific suffix PDRVT corresponds to the WSON-6 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage does not exceed the 3.3 V maximum limit during operation. Check humidity sensitivity levels for proper storage and handling requirements according to industry standards.

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

Select this component when a fixed 2.8 V rail is required with minimal quiescent current draw. The 500 mA output capability supports moderate load demands while maintaining low dropout performance. Consider the WSON-6 package for space-constrained PCB layouts. Verify that the input voltage range aligns with the available power source, particularly noting the low minimum input specification.

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

This part belongs to the TPS7A11 family of ultra-low-IQ LDO regulators designed for low-voltage applications. Unlike higher-current variants such as the TPS7A10 series, this model offers 500 mA output in a compact WSON-6 package. It shares architectural similarities with other fixed-output members like the TPS7A1130 but differs in output voltage setting.
