6 Electrical Characteristics
6.1 DC Electrical Characteristics
T AMB = -40°C to +85°C, V BATT = 1.2V, V OUT = V OUT(NOM) , SHDNN = V OUT , R LOAD = ∞ , unless otherwise noted. Typical values are at TA =
25°C.(unless otherwise specified). Limits are 100% production tested at T AMB = 25oC. Limits over the operating temperature range are
guaranteed by design.
