LM140LQML LM140LQML Series 3-Terminal Positive Regulators Literature Number: SNVS381 LM140LQML Series 3-Terminal Positive Regulators General Description The LM140L series of three terminal positive regulators is available with several fixed output voltages making them useful in a wide range of applications. The LM140LA is an improved version of the LM78LXX series with a tighter output voltage tolerance (specified over the full military temperature range), higher ripple rejection, better regulation and lower quiescent current. The LM140LA regulators have 2% VOUT specification, 0.04%/V line regulation, and 0.01%/mA load regulation. When used as a zener diode/resistor combination replacement, the LM140LA usually results in an effective output impedance improvement of two orders of magnitude, and lower quiescent current. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regulation. The voltages available allow the LM140LA to be used in logic systems, instrumentation, Hi-Fi, and other solid state electronic equipment. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. With adequate heat sinking the regulator can deliver 100 mA output current. Current limiting is included to limit the peak output current to a safe value. Safe area protection for the output transistor is provided to limit internal power dissipa- tion. If internal power dissipation becomes too high for the heat sinking provided, the thermal shut-down circuit takes over, preventing the IC from overheating.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), JA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax - TA)/JA or the number given in the Absolute Maximum Ratings, whichever is lower. Note 3: Human body model, 100pF discharged through 1.5K Note 4: It is recommended that a minimum load capacitor of 0.01 F be used to limit the high frequency noise bandwidth. 5 www.national.com LM140LQML Series LM140LA-15 Electrical Characteristics DC Parameters LM140LQML Series Typical Performance Characteristics Maximum Average Power Dissipation Maximum Average Power Dissipation 20155307 20155308 Peak Output Current Dropout Voltage 20155310 20155311 Output Impedance Ripple Rejection 20155313 20155312 www.national.com 6 LM140LQML Series Typical Performance Characteristics (Continued) Quiescent Current Quiescent Current 20155315 20155314 Typical Applications (Note 4) Fixed Output Regulator 20155305 *Required if the regulator is located far from the power supply filter. **See note 3 in the electrical characteristics table.
