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.

Regulator

• 3.3-V/Adjustable Output

• Fast Transient Response

• 3% Tolerance Over Load and Temperature

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.

TPS767D301-EP SGLS327A – FEBRUARY 2006 – REVISED APRIL 2010 www.ti.com Regulator Protection The TPS767D301-EP PMOS-pass transistor has a built-in back-gate diode that safely conducts reverse currents when the input voltage drops below the output voltage (e.g., during power down). Current is conducted from the output to the input and is not internally limited. When extended reverse voltage is anticipated, external limiting may be appropriate.
