TCR3UG18A,LF(S

TCR3UG18A,LF(S is a TCR3UG series CMOS general-purpose single-output voltage regulator with an on/off control input, featuring ultra low quiescent bias current and low dropout voltage. It has a low dropout voltage of 155mV (3.3V output, IOUT = 300mA). As small ceramic input and output capacitors 1μF can be used with the TCR3UG series, this device is ideal for portable applications that require high-density board assembly such as cellular phones, IoT equipment and wearable devices. Applications include power IC developed for portable applications, IoT equipment and wearable devices.
