1A 0.5V Ultra LDO Voltage Regulator With Adjustable Soft-Start
The XC6603 series from Torex is a high speed and highly accurate LDO which can supply up to 1A of output current while consuming only 100µA. With the help of a bias voltage that can be set between 2.5V and 6.0V, the XC6603 operates with input voltages from 0.5V to 3.0V and is readily available with fixed output voltages from 0.5V to 1.8V in 0.1V increments.
It is thanks to its integrated N-ch driver transistor that the minimum input and output voltages of the XC6603 can be much lower than more traditional LDOs with their integrated P-ch transistors. Another advantage of the XC6603 integrated N-ch driver transistor is that it dramatically reduces the on-resistance at low output voltages, leading to dropout voltages as low as 155mV @ 1A with VOUT=1.2V (VBIAS=3.6V). This makes the XC6603 ideally suited for low input/output voltage applications which require high output current and extended battery life.
Available in a tiny USP-6C package as well as a standard SOT-26W.
