TCR3DM105,LF(SE

The TCR3DM series are CMOS general-purpose single-output voltage regulators with an on/off control input, featuring low dropout voltage, low output noise voltage and low inrush current. These voltage regulators are available in fixed output voltages between 1.0 V and 4.5 V and capable of driving up to 300 mA. They feature over-current protection, over-temperature protection, Inrush current protection circuit and Auto-discharge function. The TCR3DM series are offered in the ultra small plastic mold package DFN4/DFN4E (1.0 mm×1.0 mm; t 0.58 mm). It has a low dropout voltage of 210 mV (2.5 V output, lOUT = 300 mA) with low output noise voltage of 38 μVrms (2.5 V output) and a load transient response of only ΔVOUT = ±80 mV (ΔlOUT = 1 mA ⇔ 300 mA, COUT = 1.0 μF). As small ceramic input and output capacitors can be used with the TCR3DM series, these devices are ideal for portable applications that require high-density board assembly such as cellular phones.
