The LMV7219 is a low-power, high-speed comparator with internal hysteresis. The LMV7219 operating voltage ranges from 2.7V to 5V with push/pull rail-to-rail output. This device achieves a 7ns propagation delay while consuming only 1.1mA of supply current at 5V. The LMV7219 inputs have a common mode voltage range that extends 200mV below ground, allowing ground sensing. The internal hysteresis ensures clean output transitions even with slow-moving inputs signals. The LMV7219 is available in the SC70-5 and SOT23-5 pack- ages, which are ideal for systems where small size and low power are critical.

The LME series of DC-DC converters are optimised for low-power operation. Due to the low quiescent current they are able to offer efficiencies up to 75%. The use of advanced magnetics ensures a minimal quiescent current of around 2.5mA which ensures that efficiency is maximised in low power applications. They are ideally suited to generating a negative supply where only a positive rail exists.

This datasheet mainly introduces the basic principle, characteristic parameters, usage methods and circuit application examples of the LM2594/LM2594HV series switching regulators.

LM45B/LM45C SOT-23 Precision Centigrade Temperature Sensors. This sensor does not require any external calibration or trimming to provide accuracies of ±2°C at room temperature and ±3°C over a full −20 to +100°C temperature range.

LM140L series 3-Terminal Positive Regulators is a three-terminal positive voltage regulator with multiple fixed output voltages, which makes it useful in a wide range of applications. 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. 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 primarily designed as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. LM140LA, LM340LA are available in the low profile metal three lead TO-39 (H) package and the LM340LA are also available in the plastic TO-92 (Z) package. With adequate heat sinking the regulator can deliver 100 mA output current. Current limiting is in the input.

The LLQ1608 series is a wirewound ceramic chip inductor that conforms to the EIA standard 0603 footprint and delivers superb Q and SRF performance with high inductance tolerance.
