Preliminary and all contents are subject to change without prior notice Note 1: Exceeding the absolute maximum rating may damage the device. 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 Table 1 and the “Thermal Considerations” 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 100μA 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 2% below its nominal value measured at 1V differential. Typical Application

Preliminary and all contents are subject to change without prior notice Application Hints Like any low dropout regulator, SE5169 requires external capacitors to ensure stability. The external capacitors must be carefully selected to ensure performance. Thermal Considerations It is important that the thermal limit of the package is not exceeded. The SE5169 has built-in thermal protection. When the thermal limit is exceeded, the IC will enter protection, and V OUT will be pulled to ground. The power dissipation for a given application can be calculated as following: The power dissipation (P D) is PD = IOUT * [VIN – VOUT] The thermal limit of the package is then limited to P D(MAX) = [T J – T A]/ΘJA where T J is the junction temperature, TA is the ambient temperature, and Θ JA is around 250°C/W for SE5169. SE5169 is designed to enter thermal protection at 150°C. For example, if T A is 25°C then the maximum P D is limited to about 0.5W. In other words, if I OUT(MAX) = 300mA, then [VIN – VOUT] cannot exceed 1.67V. Input Capacitor An input capacitor of at least 1 μF is required. Ceramic or Tantalum can be used. The value can be increase without upper limit. Output Capacitor An output capacitor is required for stability. It must be placed no more than 1 cm away from the V OUT pin, and connected directly between VOUT and GND pins. The minimum value is 1 μF but may be increase without limit.
