6 Electrical Characteristics

DC Electrical Characteristics

TAMB = -40°C to +85°C, VBATT = 1.2V, VOUT = VOUT(NOM), SHDNN = VOUT, RLOAD = ∞, unless otherwise noted. Typical

values are at TA = 25°C.(unless otherwise specified). Limits are 100% production tested at TAMB = 25ºC. Limits over

the operating temperature range are guaranteed by design.
