TCR3DG11,LF

The TCR3DG 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 overcurrent protection, thermal shutdown, Inrush current reduction and Auto-discharge. The TCR3DG series are offered in the ultra small package WCSP4E (0.645 mm×0.645 mm; t 0.40 mm). It has a low dropout voltage of 160 mV (3.2 V output, lOUT = 300 mA) with low output noise voltage of 38 μVrms (2.5 V output) and a load transient response of only ∠VoUT = ±80 mV (IOUT = 1 mA ⇔ 300 mA, COUT = 1.0 μF). Weight : 0.34 mg (Typ.) As small ceramic input and output capacitors can be used with the TCR3DG series, these devices are ideal for portable applications that require high-density board assembly such as cellular phones.
