Torex has integrated internal phase compensation circuitry in its latest low-dropout voltage regulator, so removing the need for expensive output capacitors.

As a result, even with no capacitor, the XC6503 is designed to deliver output currents up to 500mA and is readily available with fixed output voltages from 1.2V to 5.0V in 0.05V increments.

The devices has a PSRR of 55dB at 1kHz, draws 15µA in operation and less than 0.1µA in standby mode. 

The voltage-drop is also optimised to maximise battery life with only 300mV required at 500mA.

The LDO can also work with an output capacitor if required and includes an optional CL discharge function to immediately discharge of the Output Capacitor, ensuring that the VOUT pin drops down to ground quickly, should the XC6503 be turned off via the CE pin.

The USP-4 package measures 1.2mm x 1.6mm x 0.6mm.
