... SC70 and 5-pin SOT23 packages. The 5-pin SC70 is approximately half the size of the 5-pin SOT23. The LMV393 is available in 8-pin SOIC and MSOP. The LMV339 is available in 14-pin SOIC and TSSOP. The LMV331/393/339 is the most cost-effective solution where space, low voltage, low power and price are the pri- mary specification in circuit design for portable consumer products ...
