TCR3DG11

TCR3DG series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR3DG series 300 mA CMOS Low Drop-Out Regulator with inrush current protection circuit 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 over-current protection, thermal shut down function, Inrush current protection circuit and Auto-discharge function. The TCR3DG series are offered in the ultra small package WCSP4E(0.645mm x 0.645mm; t 0.40mm). It has a low dropout WCSP4E voltage of 160 mV (3.2 V output, IOUT = 300 mA) with low output Weight : 0.34 mg (Typ.) 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). 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. Features Low Drop-Out voltage VIN-VOUT = 160 mV (Typ.) at 3.2 V-output, IOUT = 300 mA Low output noise voltage VNO = 38 μVrms (Typ.) at 2.5 V-output, IOUT = 10 mA, 10 Hz <= f <= 100 kHz Fast load transient response (⊿VOUT = ±80 mV (Typ.) at IOUT = 1 ⇔ 300 mA, COUT =1.0 μF ) High ripple rejection ( R.R = 70 dB (Typ.) at 2.5V-output, IOU...
