TPS767D325PWP

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

The TPS767D325PWP is a dual-output low-dropout linear voltage regulator manufactured by Texas Instruments. It provides fixed positive output voltages of 2.5V and 3.3V with a maximum continuous output current of 1A per channel. The device operates from an input voltage range up to 10V and features a typical dropout voltage of 350mV at full load. It incorporates ultra-low quiescent current, typically 85µA, and includes power-on reset signals for system supervision. The component is housed in a 28-pin HTSSOP package and supports operation across a temperature range of -40°C to +125°C.

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

Verify the specific suffix 'PWP' corresponds to the 28-pin HTSSOP PowerPAD package configuration. Confirm RoHS compliance status matches REACH regulations for the target market. Ensure ordering documentation specifies the tube packaging variant rather than tape-and-reel alternatives. Validate that the manufacturer part number aligns with the required 2.5V/3.3V fixed output combination.

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

Select this component when simultaneous 2.5V and 3.3V supplies are required from a single input source. It is suitable for designs prioritizing low static current and integrated reset functionality. Consider thermal dissipation requirements given the 1A output capability per channel. Verify that the application utilizes low ESR capacitors to maintain stability with the fast transient response design.
