DESCRIPTION/ORDERING INFORMATION
Each fixed-voltage precision regulator in the TL780 series is capable of supplying 1.5 A of load current. A unique
temperature-compensation technique, coupled with an internally trimmed band-gap reference, has resulted in
improved accuracy when compared to other three-terminal regulators. Advanced layout techniques provide
excellent line, load, and thermal regulation. The internal current-limiting and thermal-shutdown features
essentially make the devices immune to overload.

(1) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. Due to variations in
individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power
levels slightly above or below the rated dissipation.
(2) For packages with exposed thermal pads, such as QFN, PowerPAD™, or PowerFLEX, θJP is defined as the thermal resistance between
the die junction and the bottom of the exposed pad.

Operation With a Load Common to a Voltage of Opposite Polarity
In many cases, a regulator powers a load that is not connected to ground, but instead, is connected to a voltage
source of opposite polarity (e.g., operational amplifiers, level-shifting circuits, etc.). In these cases, a clamp diode
should be connected to the regulator output as shown in Figure 4. This protects the regulator from output
polarity reversals during startup and short-circuit operation.

Figure 4. Output Polarity-Reversal-Protection Circuit
Reverse-Bias Protection
Occasionally, the input voltage to the regulator can collapse faster than the output voltage. This, for example,
could occur when the input supply is crowbarred during an output overvoltage condition. If the output voltage is
greater than approximately 7 V, the emitter-base junction of the series pass element (internal or external) could
break down and be damaged. To prevent this, a diode shunt can be employed, as shown in Figure 5.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
