... Portable medical devices RF, PLL, VCO, and clock power supplies GENERAL DESCRIPTION The ADP150 is an ultralow noise (9 µV), low dropout, linear regulator that operates from 2 5.5 V and provides up to 150 mA of output current. The low 105 mV dropout voltage at 150 mA load improves efficiency and allows operation over a wide input voltage range ...

... Consider the case where a hard short from VOUT to GND occurs. At first, the ADP150 limits current so that only 260 mA is conducted 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 ...

... PCB LAYOUT CONSIDERATIONS Heat dissipation from the package can be improved by increasing the amount of copper attached to the pins of the ADP150. However, as listed in Table 7, a point of diminishing returns is reached eventually, beyond which an increase in the copper size does not yield significant heat dissipation benefits. ...
