TCR3DM series2017-06-201TOSHIBA CMOS Linear Integrated Circuit Silicon MonolithicTCR3DM series300 mA CMOS Low Drop-Out Regulator with inrush current protection circuitThe TCR3DM series are CMOS general-purpose single-outputvoltage regulators with an on/off control input, featuring low dropoutvoltage, low output noise voltage and low inrush current.These voltage regulators are available in fixed output voltagesbetween 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 moldpackage DFN4 (1.0 mm x 1.0 mm; t 0.58 mm). It has a low dropoutvoltage of 210 mV (2.5 V output, IOUT = 300 mA) with low outputnoise voltage of 38μVrms (2.5 V output) and a load transientresponse of onlyΔVOUT = ±80 mV ( IOUT = 1 mA⇔300 mA, COUT=1.0μF).As small ceramic input and output capacitors can be used with theTCR3DM series, these devices are ideal for portable applications that require high-density board assembly such ascellular phones.Features• Low Drop-Out voltageVIN-VOUT = 210 mV (typ.) at 2.5 V-output, IOUT = 300 mAVIN-VOUT = 270 mV (typ.) at 1.8 V-output, IOUT = 300 mAVIN-VOUT = 490 mV (typ.) at 1.2 V-output, IOUT = 300 mA• Low output noise voltageVNO = 38μVrms (typ.) at 2.5 V-output, IOUT = 10 mA, 10 Hz ≤ f ≤ 100 kHz• Fast load transient response (ΔVOUT = ±80 mV (typ.) at IOUT = 1 mA⇔ 300 mA, COUT =1.0 μF )• High ripple rejection ( R.R = 70 dB (typ.) at 2.5V-output, IOUT = 10 mA, f =1kHz )• Over-current protection• Over-temperature protection• Inrush current protection circuit• Auto-discharge function• Pull down connection between CONTROL and GND• Ceramic capacitors can be used ( CIN = 1.0μF, COUT =1.0 μF )• Ultra small package DFN4 (1.0 mm x 1.0 mm ; t 0.58 mm )BOTTOM VIEW ILLUSTRATIONDFN4Weight : 1.3 mg ( typ.)Start of commercial production2013-03
