description/ordering information

NC − No internal connection

This series of fixed-voltage integrated-circuit

voltage regulators is designed for a wide range of

applications. These applications include on-card

regulation for elimination of noise and distribution

problems associated with single-point regulation.

In addition, they can be used with power-pass

elements to make high-current voltage regulators.

One of these regulators can deliver up to 100 mA

of output current. The internal limiting and

thermal-shutdown features of these regulators

essentially make them immune to overload. When

used as a replacement for a Zener diode-resistor

combination, an effective improvement in output

impedance can be obtained, together with lower

bias current.

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 6. This protects the regulator from output

polarity reversals during startup and short-circuit operation.

Figure 6. Output Polarity-Reversal-Protection Circuit

reverse-bias protection

Occasionally, the input voltage to the regulator can collapse faster than the output voltage. This can occur, for

example, 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 7.

Eco Plan

-

The planned eco-friendly classification: Pb-Free (RoHS) 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.

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)

(3)

MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder

temperature.
