LTC3330 Datasheet, PDF (5/20 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.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTC3330E is tested under pulsed load conditions such that
T_J ≈ T_A. The LTC3330E is guaranteed to meet specifications from 0°C to
85°C. The LTC3330I is guaranteed over the –40°C to 125°C operating
junction temperature range. Note that the maximum ambient temperature
consistent with these specifications is determined by specific operating
conditions in conjunction with board layout, the rated package thermal
impedance and other environmental factors.
Note 3: T_J is calculated from the ambient T_A and power dissipation PD
according to the following formula: T_J = T_A + (P_D • θ_JA).
Note 4: Dynamic supply current is higher due to gate charge being
delivered at the switching frequency.
