• Controlled Baseline
– One Assembly/Test Site, One Fabrication
Site
• Extended Temperature Performance of –55°C
to 125°C
• Enhanced Diminishing Manufacturing Sources
(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.

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.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low and is directly
proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the
quiescent current is very low and independent of output loading (typically 85 mA over the full range of output
current, 0 mA to 1 A). These two key specifications yield a significant improvement in operating life for
battery-powered systems. This LDO device also features a sleep mode; applying a TTL high signal to enable
(EN) shuts down the regulator, reducing the quiescent current to 1 mA at TJ = 25°C.
The RESET output of the TPS767D301-EP initiates a reset in microcomputer and microprocessor systems in the
event of an undervoltage condition. An internal comparator in the TPS767D301-EP monitors the output voltage
of the regulator to detect an undervoltage condition on the regulated output voltage.
The TPS767D301-EP is offered in an adjustable version (programmable over the range of 1.5 V to 5.5 V). Output
voltage tolerance is specified as a maximum of 3% over line, load, and temperature ranges. The
TPS767D301-EP is available in a 28-pin PWP (TSSOP) package. The device operates over a junction
temperature range of –55°C to 125°C.
