ESD Caution Notice
National Semiconductor recommends that all integrated circuits be handled with appropriate ESD precautions. Failure to observe
proper ESD handling techniques can result in damage to the device.
Electrical Characteristics (Note 3, Note 9)
Limits in standard typeface are for T_J = 25°C. Limits in boldface type apply over the full operating junction temperature range (-30°
C ≤ T_J ≤ +125 °C). Unless otherwise noted, specifications apply to the LM2759 Typical Application Circuit (pg.1) with V_IN = 3.6V,
V_TX = 0V, V_STROBE = 0V, C_IN = C₁ = C₂ = 2.2 µF, C_OUT = 4.7 µF. (Note 10)
