TPS799285DDCT

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

The TPS799285DDCT is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by Texas Instruments. It provides a fixed output voltage of 2.85V with a maximum continuous output current of 200mA. The device operates within an input voltage range of 2.7V to 6.5V and features a typical quiescent current of 40µA. It utilizes a SOT-23-Thin-5 surface-mount package. Key electrical characteristics include a maximum dropout voltage of 175mV at full load, a power supply rejection ratio (PSRR) ranging from 70dB to 38dB across frequencies of 100Hz to 100kHz, and line/load regulation of 0.02%/V and 0.002%/mA respectively.

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

Verify the specific suffix 'DDCT' corresponds to the tape-and-reel packaging configuration rather than cut-tape or other variants. Confirm that the fixed 2.85V output aligns with the target circuit design requirements. Ensure compatibility with the SOT-23-Thin-5 footprint during PCB layout. Check for any recent Product Change Notifications regarding assembly sites or material composition updates.

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

Select this component when a fixed 2.85V rail is required with high PSRR performance. Compare against other TPS799 series variants if different output voltages are needed. Consider the thermal dissipation capabilities given the small package size and maximum power dissipation limits. Evaluate the input voltage headroom to ensure operation remains within the specified dropout characteristics under all load conditions.
