TCR2BF series, TCR2BE series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR2BF series TCR2BE series 200 mA CMOS Low Drop-Out Regulator with Auto-discharge The TCR2BF series and TCR2BE series are CMOS general-purpose single-output voltage regulators with an on/off control input, featuring low dropout voltage and low quiescent bias current. These voltage regulators can be enabled and disabled via the CONTROL pin. These voltage regulators are available in fixed output voltages between 1.0 V and 5.0 V in SMV package, 1.0 to 3.6V in ESV package, and capable of driving up to 200 mA. They feature overcurrent protection and auto-discharge function. The TCR2BF series and TCR2BE series are offered in the compact SMV (SOT-25)(SC-74A) and ESV (SOT-553) and allow the use of small ceramic input and output capacitors. Thus, these devices are ideal for portable applications that require high-density board assembly such as cellular phones. SMV ESV Weight: SMV (SOT-25)(SC-74A) : 16 mg (typ.)

However, because of the type of the capacitors, there might be unexpected thermal features. Please consider application condition for selecting capacitors. And Toshiba recommend the ESR of ceramic capacitor is under 10 Ω. ● Mounting The long distance between IC and output capacitor might affect phase assurance by impedance in wire and inductor. For stable power supply, output capacitor need to mount near IC as much as possible. Also GND pattern need to be large and make the wire impedance small as possible. ● Permissible Loss Please have enough design patterns for expected maximum permissible loss. And under consideration of surrounding temperature, input voltage, and output current etc, we recommend proper dissipation ratings for maximum permissible loss; in general maximum dissipation rating is 70 to 80 percent. ● Overcurrent Protection Circuit Overcurrent protection circuit is designed in these products, but this does not assure for the suppression of uprising device operation. If output pins and GND pins are shorted out, these products might be break down. In use of these products, please read through and understand dissipation idea for absolute maximum ratings from the above mention or our ‘Semiconductor Reliability Handbook’. Then use these products under absolute maximum ratings in any condition. Furthermore, Toshiba recommend inserting failsafe system into the design. 7 2011-06-06 TCR2BF series, TCR2BE series Representative Typical Characteristics 1) Output Voltage vs. Input Voltage VOUT=1.8V VOUT=1.0V 4.0 2.0 CIN = 0.1 μF, COUT = 1 μF (V) IOUT = 50mA IOUT = 150mA 0.5 0 0 1 2 3 Input voltage 4 VIN 5 IOUT = 10mA 2.0 Output voltage Output voltage IOUT = 10mA 1.0 3.0 VOUT 1.5 VOUT (V) CIN = 0.1 μF, COUT = 1 μF IOUT = 50mA 1.0 IOUT = 150mA 0 0 6 1 2 3 Input voltage (V) 4 VIN 5 6 (V) VOUT=3.0V 4.0 3.0 Output voltage VOUT (V) CIN = 0.1 μF, COUT = 1 μF IOUT = 10mA 2.0 IOUT = 50mA IOUT = 150mA 1.0 0 0 1 2 3 Input voltage 4 VIN 5 6 (V) 2) Output Voltage vs. Output Current VOUT=1.8V VOUT=1.0V 1.9 VIN = 2.8V, CIN = 0.1 μF, COUT = 1 μF CIN = 0.1 μF, COUT = 1 μF (V) VIN = 2.0 V, 1.0 0.9 0 Output voltage Output voltage VOUT VOUT (V) 1.1 20 40 60 80 1.7 0 100 120 140 160 180 200 Output current IOUT 1.8 (mA) 20 40 60 80 100 120 140 160 180 200 Output current 8 IOUT (mA) 2011-06-06 TCR2BF series, TCR2BE series VOUT=3.0V 3.1 VIN = 4.0V, Output voltage VOUT (V) CIN = 0.1 μF, COUT = 1 μF 3.0 2.9 0 20 40 60 80 100 120 140 160 180 200 Output current IOUT (mA) 3) Output Voltage vs. Ambient Temperature VOUT=1.0V VOUT=1.8V 1.1 VIN = 2.8 V, CIN = 0.1 μF, COUT = 1 μF CIN = 0.1 μF, COUT = 1 μF (V) VIN = 2.0 V, IOUT = 50mA VOUT 1.05 Output voltage Output voltage VOUT (V) 1.9 1.0 0.95 0.9 −50 −25 0 25 Ambient temperature 50 Ta 75 1.8 1.75 1.7 −50 100 (°C) IOUT = 50mA 1.85 −25 0 25 Ambient temperature 50 Ta 75 100 (°C) VOUT=3.0V 3.1 VIN = 4.0 V, Output voltage VOUT (V) CIN = 0.1 μF, COUT = 1 μF IOUT = 50mA 3.05 3.0 2.95 2.9 −50 −25 0 25 Ambient temperature 50 Ta 75 100 (°C) 9 2011-06-06 TCR2BF series, TCR2BE series 4) Dropout Voltage vs. Output Current VOUT=1.8V VOUT=1.0V 500 CIN = 0.1 μF, COUT = 1 μF VIN - VOUT (mV) VIN - VOUT (mV) 1000 800 Dropout voltage Dropout voltage 600 400 200 0 0 20 40 60 80 100 120 140 160 180 Output current IOUT CIN = 0.1 μF, COUT = 1 μF 400 300 200 100 0 0 200 20 40 60 80 100 120 140 160 180 Output current (mA) IOUT 200 (mA) VOUT=2.5V VIN - VOUT (mV) 500 CIN = 0.1 μF, COUT = 1 μF 400 Dropout voltage 300 200 100 0 0 20 40 60 80 100 120 140 160 180 Output current IOUT 200 (mA) 5) Quiescent Current vs. Input Voltage VOUT=1.0V VOUT=1.8V 120 120 60 40 20 0 0 (μA) 100 IB CIN = 0.1 μF, COUT = 1 μF IOUT = 0mA 80 Quiescent current (μA) 80 Quiescent current 100 IB CIN = 0.1 μF, COUT = 1 μF 1 2 3 Input voltage 4 VIN 5 60 40 20 0 6 (V) IOUT = 0mA 0 1 2 3 Input voltage 10 5 4 VIN 6 (V) 2011-06-06 TCR2BF series, TCR2BE series VOUT=3.0V 180 (μA) 120 Quiescent current 150 IB CIN = 0.1 μF, COUT = 1 μF IOUT = 0mA 90 60 30 0 0 1 2 3 Input voltage 5 4 VIN 6 (V) 6) Quiescent Current vs.Ambient Temperature VOUT=1.0V 100 VOUT=1.8V 100 VIN = 2.0 V, VIN = 2.8 V, (μA) CIN = 0.1 μF, COUT = 1μF, IOUT = 0mA IB Quiescent current Quiescent current IB (μA) CIN = 0.1 μF, COUT = 1μF, IOUT = 0mA 50 0 −50 −25 0 25 Ambient temperature 50 Ta 75 50 0 −50 100 (°C) −25 0 25 Ambient temperature 50 Ta 75 100 (°C) VOUT=3.0V 100 VIN = 4.0 V, Quiescent current IB (μA) CIN = 0.1 μF, COUT = 1μF, IOUT = 0mA 50 0 −50 −25 0 25 Ambient temperature 50 Ta 75 100 (°C) 11 2011-06-06 TCR2BF series, TCR2BE series 7) Overcurrent protection characteristics (Overcurrent protection characteristic does not assure for the suppression of uprising device operation.
