TPS767D301PWP Dual LDO Regulator for DSP and Embedded Systems

TPS767D301PWP Dual LDO Regulator | 3.3V Fixed + 1.5V-5.5V Adjustable for DSP & Embedded Systems

The TPS767D301PWP is a Texas Instruments dual-output low-dropout linear regulator engineered for systems that need multiple stable voltage rails from a single chip. The part delivers one fixed 3.3V output and one adjustable output (1.5V-5.5V), with each channel rated for 1A continuous current — the right combination for powering DSP cores, mixed-voltage logic blocks, and sensor analog rails from a shared input bus.

Designed for reliability in demanding environments, the regulator operates across a wide 2.7V to 10V input range and the full -40°C to +125°C industrial temperature spectrum. Integrated protection — overheat shutdown plus a 200ms reset delay — makes the chip particularly suitable for powering sensitive digital signal processors and complex embedded systems where supply sequencing and brown-out behaviour matter.

Ultra-Low 0.35V Dropout with 85µA Quiescent Current for Efficient Power Management

• Dual-output configuration — fixed 3.3V plus adjustable 1.5V-5.5V from a single device.
• 1A per channel — handles the load currents typical of DSP cores and mixed-voltage logic.
• 0.35V dropout at 1A — efficient operation from regulated 3.3V or 5V upstream rails.
• 85µA quiescent current (1µA standby) — extends battery life in portable embedded designs.
• 200ms reset delay — clean power-up sequencing for downstream digital logic.

Where the TPS767D301PWP Fits

The natural use case is dual-rail supply for embedded DSP and FPGA designs that need a clean 3.3V I/O rail plus a tighter analog or core rail set by external resistors. The 28-HTSSOP exposed-pad package gives strong thermal performance for the 1A-per-channel rating, and the wide input range covers common 5V and 9-12V supply buses without external preregulation. Industrial and automotive embedded designs that need durable, low-noise dual rails sit naturally on this part.
