ADP2300/ADP2301 Data Sheet ABSOLUTE MAXIMUM RATINGS Table 2. Parameter Rating THERMAL RESISTANCE
VIN, EN −0.3 V to +28 V θJA is specified for the worst-case conditions, that is, a device SW −1.0 V to +28 V soldered in a circuit board for surface-mount packages. BST to SW −0.6 V to +6 V BST −0.3 V to +28 V
Table 3. Thermal Resistance1
FB −0.3 V to +3.3 V
Package Type θ θ Unit JA JC
Operating Junction Temperature Range −40°C to +125°C 6-Lead TSOT 186.02 66.34 °C/W Storage Temperature Range −65°C to +150°C 1 θ Soldering Conditions JEDEC J-STD-020 JA and θJC are measured using natural convection on a JEDEC 4-layer board.
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.
