ADP2302/ADP2303 Data Sheet ABSOLUTE MAXIMUM RATINGS Table 2. THERMAL RESISTANCE Parameter MAX Rating
θJA is specified for the worst-case conditions, that is, a device VIN, EN, PGOOD −0.3 V to +24 V soldered in a circuit board for surface-mount packages. SW −1.0 V to +24 V
Table 3. Thermal Resistance1
BST to SW −0.6 V to +6 V
Package Type θ
FB, NC −0.3 V to +6 V
JA Unit
Operating Junction Temperature Range −40°C to +125°C 8-Lead SOIC_N_EP 58.5 °C/W Storage Temperature Range −65°C to +150°C 1 JA is measured using natural convection on JEDEC 4-layer board. Soldering Conditions JEDEC J-STD-020
ESD CAUTION
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Absolute maximum ratings apply individually only, not in combination. Unless otherwise specified, all voltages are referenced to GND. Rev.
