DISSIPATION RATINGS

TPS780 Series

SBVS083B – JANUARY 2007 – REVISED MARCH 2008

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

ORDERING INFORMATION(1)

PRODUCT

VOUT

TPS780vvvxxxyyyz

VVV is the nominal output voltage for VOUT(HIGH) and corresponds to VSET pin low.

XXX is the nominal output voltage for VOUT(LOW) and corresponds to VSET pin high.

YYY is the package designator.

Z is the tape and reel quantity (R = 3000, T = 250).

Adjustable version(2)(3)

(1)

For the most current package and ordering information see the Package Option Addendum at the end of this document, or see the TI

web site at www.ti.com.

(2)

To order the adjustable version, use TPS78001YYYZ.

(3)

The device is either fixed voltage, dual-level VOUT, or adjustable voltage only. Device design does not permit a fixed and adjustable

output simultaneously.

Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may

degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond

those specified is not implied.

(2)

VEN and VVSET absolute maximum rating are VIN + 0.3V or +6.0V, whichever is less.
