FEATURES
• Controlled Baseline • 1-mA Quiescent Current During Shutdown
– One Assembly/Test Site, One Fabrication • Dual Open-Drain Power-On Reset With
Site 200-ms Delay for Each Regulator
• Extended Temperature Performance of –55°C • 28-Pin PowerPAD™ TSSOP Package
to 125°C
• Thermal Shutdown Protection for Each
• Enhanced Diminishing Manufacturing Sources Regulator
(DMS) Support
• Enhanced Product-Change Notification
• Qualification Pedigree
Component qualification in accordance with JEDEC and industry
standards to ensure reliable operation over an extended
temperature range. This includes, but is not limited to, Highly
Accelerated Stress Test (HAST) or biased 85/85, temperature
cycle, autoclave or unbiased HAST, electromigration, bond
intermetallic life, and mold compound life. Such qualification testing
should not be viewed as justifying use of this component beyond
specified
performance and environmental limits.
• Dual Output Voltages for Split-Supply
Applications
• Output Current Range of 0 mA to 1.0 A Per
Regulator
• 3.3-V/Adjustable Output
• Fast Transient Response
• 3% Tolerance Over Load and Temperature
• Dropout Voltage Typically 350 mV at 1 A
• Ultra-Low 85-mA Typical Quiescent Current
DESCRIPTION/ORDERING INFORMATION
The TPS767D301-EP dual-voltage regulator offers fast transient response, low dropout (LDO) voltages, and dual
outputs in a compact package and incorporates stability with 10-mF low-ESR output capacitors.
The TPS767D301-EP dual-voltage regulator is designed primarily for DSP applications. This device can be used
in any mixed-output voltage application, with each regulator supporting up to 1 A. Dual active-low reset (RESET)
signals allow resetting of core logic and I/O separately.
