TCR6DA series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR6DA series 200 mA Dual Outputs CMOS Low-Dropout Regulator SM6 The TCR6DA series are CMOS general-purpose dual-outputs voltage regulators with independent on/off control inputs, featuring low dropout voltage and low quiescent bias current. The TCR6DA series can be enabled and disabled via the CONTROL pin for each LDOs. These voltage regulators are available in fixed output voltages between 1.5 V and 3.3 V in 0.1-V steps and capable of driving up to 200 mA. They feature overcurrent protection. The TCR6DA series are offered in the compact SM6 (SOT-26) (SC-74) and small package UF6 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.

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 board design patterns for expected maximum permissible loss. And under consideration of surrounding temperature, input voltage, and output current etc, please apply proper dissipation ratings for maximum permissible loss. ● 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 2011-02-03 TCR6DA series Representative Typical Characteristics 1) Output Voltage vs. Input Voltage Vout=1.8V Vout=1.5V (V) CIN = 1 μF, COUT = 1 μF IOUT = 1 mA VOUT 1.5 3 1.0 Output voltage Output voltage VOUT (V) 2.0 50 mA 0.5 0 0 1 2 3 Input voltage 4 VIN 5 CIN = 1 μF, COUT = 1 μF 2.5 2 IOUT = 1 mA 1.5 1 50 mA 0.5 0 0 6 1 2 3 Input voltage (V) 4 VIN 5 6 (V) Vout=2.5V Output voltage VOUT (V) 6 CIN = 1 μF, COUT = 1 μF 5 4 3 2 IOUT = 1 mA 50 mA 1 0 0 1 2 3 Input voltage 4 VIN 5 6 (V) 2) Output Voltage vs. Output Current Vout=1.8V Vout=1.5V 1.9 VIN = 2.8V, CIN = 1 μF, COUT = 1 μF CIN = 1 μF, COUT = 1 μF (V) VIN = 2.5 V, 1.5 1.4 0 Output voltage Output voltage VOUT VOUT (V) 1.6 20 40 60 80 1.7 0 100 120 140 160 180 200 Output current IOUT 1.8 20 40 60 80 100 120 140 160 180 200 Output current (mA) 8 IOUT (mA) 2011-02-03 TCR6DA series Vout=2.5V 2.6 VIN = 3.5 V, Output voltage VOUT (V) CIN = 1 μF, COUT = 1 μF 2.5 2.4 0 20 40 60 80 100 120 140 160 180 200 Output current IOUT (mA) 3) Output Voltage vs. Ambient temperature Vout=1.5V Vout=1.8V 1.52 1.82 (V) VIN = 2.8 V, CIN = 1 μF, COUT = 1 μF VOUT 1.51 Output voltage Output voltage VOUT (V) VIN = 2.5 V, 1.5 IOUT = 50 mA 1.49 1.48 −50 −25 0 25 50 Ambient temperature Ta 75 1.8 (°C) IOUT = 50 mA 1.79 1.78 −50 100 CIN = 1 μF, COUT = 1 μF 1.81 −25 0 25 Ambient temperature 50 Ta 75 100 (°C) Vout=2.5V 2.52 Output voltage VOUT (V) VIN = 3.5V, CIN = 1 μF, COUT = 1 μF 2.51 2.5 IOUT = 50 mA 2.49 2.48 −50 −25 0 25 Ambient temperature 50 Ta 75 100 (°C) 9 2011-02-03 TCR6DA series 4) Dropout Voltage vs. Output Current Vout=2.5V Dropout voltage VIN -
