TCR2DG series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR2DG series Low Noise 200 mA CMOS Low Drop-Out Regulator in ultra small package The TCR2DG series are CMOS general-purpose single-output voltage regulators with an on/off control input, featuring low dropout voltage, low quiescent bias current and fast load transient response. These voltage regulators are available in fixed output voltages between 1.2 V and 3.6 V and capable of driving up to 200 mA. They feature overcurrent protection and thermal shut down function. The TCR2DG series is offered in the ultra small package WCSP4 ( 0.79 mm x 0.79 mm x 0.5 mm). It has a low dropout voltage of 75 mV ( 2.5 V output, I = 100 mA) with low output noise voltage of 18 OUT V (2.5 V output) and a load transient response of only rms WCSP4 V = 65 mV ( I = 1 mA150 mA, C =1.0 F). OUT OUT OUT Weight : 0.7 mg (typ.) As small ceramic input and output capacitors can be used with the TCR2DG series, these devices are ideal for portable applications that require high-density board assembly such as cellular phones.
