Torex Semiconductor has developed a new 200mA, high-speed LDO regulator XC6233 with inrush current prevention.
The input voltage range is 1.7V to 5.5V and the output voltage can be selected within a range of 1.2V to 3.6V (0.05V increments) with a high accuracy of ±1%. The series offers a low dropout voltage of 240mV (IOUT=200mA, VOUT=3.0V) and a high ripple rejection of 75dB (at 1kHz). The internal inrush current prevention circuit limits the inrush current between VIN and VOUT to 95mA or less, and thereby controls voltage fluctuations at the VIN input side. The over-current protection circuit (foldback) is included as another protective function and this activates if the output current reaches the current limit. Even if over-current occurs due to a short-circuit, for example, the foldback function limits the current to a safe 60mA (TYP.).
The small USP-4, SSOT-24, or SOT-25 package can be selected to match the application and this is an environment friendly product that complies with the EU RoHS directive and is Pb free.
