1 / 15 page TCR2DG series 2014-03-01 1 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, IOUT = 100 mA) with low output noise voltage of 18 μVrms (2.5 V output) and a load transient response of only ⊿ VOUT = ±65 mV ( IOUT = 1 mA⇔150 mA, COUT =1.0 μF). 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. Features • Low Drop-out Voltage ( VIN-VOUT = 75 mV (typ.) at 2.5 V-output, IOUT = 100 mA ) • Low quiescent bias current ( IB = 45 μA (typ.) at IOUT = 0 mA ) • Low stand-by current ( IB(OFF) = 0.1 μA (typ.) at Stand-by mode ) • Low output noise voltage VNO = 22 μVrms (typ.) at 3.0 V-output, IOUT = 10 mA, 10 Hz < f < 100 kHz VNO = 18 μVrms (typ.) at 2.5 V-output, IOUT = 10 mA, 10 Hz < f < 100 kHz VNO = 14 μVrms (typ.) at 1.2 V-output, IOUT = 10 mA, 10 Hz < f < 100 kHz • High ripple rejection ratio R.R = 75 dB (typ.) at 2.5 V-output, IOUT = 10 mA, f =1kHz R.R = 62 dB (typ.) at 2.5 V-output, IOUT = 10 mA, f =10kHz R.R = 50 dB (typ.) at 2.5 V-output, IOUT = 10 mA, f =100kHz • Fast load transient response (⊿VOUT = ±65 mV (typ.) at IOUT = 1mA ⇔ 150 mA, COUT =1.0 μF ) • Output voltage accuracy ±1.0 % • Over current protection • Thermal shut down function • Built-in inrush current reduction circuit • Pull down connection between CONTROL and GND • Ceramic capacitors can be used ( CIN = 0.47μF, COUT =1.0 μF ) • Ultra small package, WCSP4 ( 0.79 mm x 0.79 mm x 0.50 mm ) Pin Assignment (top view) WCSP4 Weight : 0.7 mg (typ.)
