· TI posits that the TPS7A24 LDO maximum dropout voltage is less than 250mV at 200mA of current, allowing it to operate more efficiently than standard linear regulators. For an LDO that provides any given output voltage, the input voltage must be somewhat larger. The dropout voltage (V DO) specifies just how much larger that input must be.

· Texas Instruments offers technical documents such as applications notes, white papers and guides that help you better understand how to use LDO regulators more efficiently, maximize LDO performance, and use our LDOs to extend the battery life of your applications.
· Current limit in an LDO is defined by establishing an upper boundary for the current supplied. Unlike a constant current source, LDOs supply current on demand but can also control the total power regulated. Current limiting is achieved through internal circuitry controlling the output stage transistors inside the LDO. See Figure 1.
