8 / 26 page  LP3996 SNVS360B – NOVEMBER 2006 – REVISED JANUARY 2008 www.ti.com Electrical Characteristics (1) (2) (continued) Unless otherwise noted, VEN = 950mV, VIN = VOUT + 1.0V, or 2.0V, whichever is higher, where VOUT is the higher of VOUT1 and VOUT2. CIN = 1 µF, IOUT = 1 mA, COUT1 = COUT2 = 1.0µF. Typical values and limits appearing in normal type apply for TA = 25°C. Limits appearing in boldface type apply over the full junction temperature range for operation, −40 to +125°C.
