LM140LQML www.ti.com SNVS381A – MARCH 2006 – REVISED MAY 2013 LM140LQML Series 3-Terminal Positive Regulators Check for Samples: LM140LQML FEATURES 1 2 Line Regulation of 0.04%/V Load Regulation of 0.01%/mA Output Voltage Tolerances of ±2% at Tj = 25°C and ±4% over the Temperature Range Output Current of 100 mA Internal Thermal Overload Protection Output Transistor Safe Area Protection Internal Short Circuit Current Limit 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 externa...
