LTC3330 Datasheet, PDF (4/20 Pages) Linear Technology – Energy Harvesting DC/DC with Battery Backup Low Noise LDO Post Regulator

LTC3330
Electrical Characteristics The l denotes the specifications which apply over the specified operating
junction temperature range, otherwise specifications are at T_A = 25°C (Note 2). V_IN = 5V, BAT = 3.6V, SCAP = OV, LDO_IN = 0V unless
otherwise specified.
