2008 www.ti.com 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)(2) PRODUCT VOUT TPS781vvvxxxyyyz 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(3)(4) (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) Additional output voltage combinations are available on a quick-turn basis using innovative, factory EPROM programming. Minimum-order quantities apply;
contact your sales representative for details and availability. (3) To order the adjustable version, use TPS78101YYYZ. (4) The device is either fixed voltage, dual-level VOUT, or adjustable voltage only. Device design does not permit a fixed and adjustable output simultaneously. At TJ = C40°C to +125°C, unless otherwise noted. All voltages are with respect to GND.

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. DERATING FACTOR BOARD PACKAGE RθJC RθJA ABOVE TA = +25°C TA <
