... THERMAL DATA Absolute maximum ratings apply only individually, not in combi- nation. The ADP130 may be damaged when junction temperature limits are exceeded. Monitoring ambient temperature does not guarantee that the junction temperature is within the specified temperature limits. In applications with high power dissipation and poor thermal resistance, the maximum ambient temperature may need to be derated ...

... EN Figure 33. Internal Block Diagram The ADP130 is available in output voltages ranging from 0 3.0 V. The ADP130 uses the EN pin to enable and disable the VOUT pin under normal operating conditions. When EN is high, VOUT turns on. When EN is low, VOUT turns off. For auto- matic startup, EN can be tied to VBIAS. ...

... ADP130. Transient response to changes in load current is also affected by output capacitance. Using a larger value of output capacitance improves the transient response of the ADP130 to large changes in load current. Figure 34 and Figure 35 show the transient responses for output capacitance values of 1 µF and 10 µF, respectively. ...

... The ADP130 uses an internal soft start to limit the inrush current when the output is enabled. The start-up time for the 0.8 V option is approximately 180 µs from the time at which the EN active threshold is crossed to when the output reaches 90% of its final value. The start-up time depends somewhat on the output voltage setting and increases slightly as the output voltage increases ...

... Consider the case where a hard short from VOUT to GND occurs. At first, the ADP130 current limits so that only 550 mA is con- ducted into the short. If self-heating of the junction is great enough to cause its temperature to rise above 150°C, thermal shutdown activates, turning off the output and reducing the output current to zero. As the junction temperature cools and drops below 135° ...
