TOREX 500mA HIGH-SPEED, LOW-NOISE LDO REQUIRES NO LOAD CAPACITOR

The TOREX XC6503 series eliminates the need for expensive output capacitors and reduces the required PCB layout area. Even without a capacitor, the XC6503 can deliver output currents up to 500mA, and it is currently available with fixed output voltages from 1.2V to 5.0V in 0.05V increments.

Performance is always important for an LDO regulator, and the XC6503 features a fast settling time and high PSRR (55dB @ 1kHz) while consuming only 15uA in operation and less than 0.1uA in standby mode. In addition, the voltage drop has been optimized to maximize battery life, with a low 300mV at 500mA.

The XC6503 is also very safe, thanks to integrated short circuit protection, thermal shutdown and a built-in current limiter. At the same time, this LDO can operate with an output capacitor if required, and it includes an optional output discharge (CL) function to immediately discharge the output capacitor. This ensures that the output voltage quickly drops to zero should the XC6503 be turned off via the CE pin.

The tiny USP-4 package – measuring a mere 1.2mm x 1.6mm x 0.6mm – makes the XC6503 ideal for space constrained applications. However, larger SOT25, SOT89-5 or TO252 packages are also available for applications that require additional power dissipation.
