Note 2: The device is not guaranteed to function outside its operating rating. Note 3: The maximum allowable power dissipation at any TA (ambient temperature) is calculated using: PD(MAX) = (TJ(MAX) – TA)/ΘJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. See “Thermal Consideration” section for details Note 4: Output voltage temperature coefficient is the worst case voltage change divided by the total temperature range. Note 5: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range from 0.1mA to 300mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Note 6: Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured at 0.8V differential. Note 7: The Cin or Cout should be chosen carefully.

The external capacitors must be carefully selected to SE5509B Thermal Considerations It is important that the thermal limit of the package is not exceeded. The SE5509B has built-in thermal protection. to ground. When the thermal limit is exceeded, The power dissipation for a given the IC will enter protection, and VOUT will be pulled application can be calculated as following: The power dissipation (PD) is PD = IOUT * [VIN – VOUT] The thermal limit of the package is then limited to PD(MAX) = [TJ – TA]/ΘJA where TJ is the junction temperature, TA is the ambient temperature, and ΘJA is around 230°C/W for SE5509B. SE5509B is designed to enter thermal protection at 150°C. For example, if TA is 25°C then the maximum PD is limited to about 0.6W. In other words, if IOUT(MAX) = 300mA, then [VIN – VOUT] cannot exceed 2V. Input Capacitor An input capacitor of at least 1μF is required. The inexpensive Electrolytic capacitor is preferred. The value can be increased without upper limit. Output Capacitor An output capacitor is required for stability. It must be placed no more than 1 cm away from the VOUT pin, and connected directly between VOUT and GND pins. The inexpensive Electrolytic capacitor is recommended. The minimum value is 1μF but may be increased without limit.
