The output capacitor is required between output and GND to prevent oscillation. 2. The ESR of capacitor must be defined in ESR stability area. It is possible to use a ceramic capacitor without ESR resistance for output. The ceramic capacitor must be used more than 1.0µF and B type (X5R) temperature characteristics. 3. The wire of Vcc and GND is required to print full ground plane for noise and stability. 4. The input capacitor must be connected a distance of less than 1cm from input pin. 5. The capacitor is connected to Cn must have low leakage current characteristics, because Cn pin is high impedance. The rise time will chage depending on the capacitance value. 6. In case the output voltage is above the input voltage, the overcurrent flow by internal parasitic diode from output to input. In such application, the external bypass diode must be connected between output and input pin. MITSUMI Low-Saturation 300mA Regulators MM159X Series Characteristics 3.0 (2.5V product Except where noted therwise, Ta=25°C, VIN=VO+2V, VCONT=VIN, CIN=1.0µF, CO=1.0µF) Input Voltage-Output Voltage Output Voltage VO (V) No Load Input Current 5.0 RL=∞ 2.5 2.0 1.5 1.0 0.5 0.0 0 1 2 3 4 5 RL=2.5kΩ RL=8.3Ω RL=25Ω Input Current IIN (mA) 4.0 3.0 2.0 1.0 0.0 0 2 4 6 8 10 12 Input Voltage VIN (V) Input Voltage VIN (V) Load Regulation Load Regulation Vload (mV) 30 20 10 0 -10 -20 -30 0 50 100 150 200 250 300 Line Regulation VO (mV) 10 5 0 -5 -10 4 5 6 7 8 9 10 11 12 13 RL=2.5kΩ Load Current IOUT (mA) Line regulation Input Voltage VIN (V) Drop Voltage 0.50 VIN=2.3V Output Voltage(IO=0mA) Output Voltage VOUT (V) 2.7 2.6 2.5 2.4 2.3 2.2 -50 -25 RL=∞ Drop Voltage (V) 0.40 0.30 0.20 0.10 0.00 0 100 200 300 400 500 0 25 50 75 100 125 150 IOUT (mA) Ambient Temperature Ta (ºC) MITSUMI Low-Saturation 300mA Regulators MM159X Series Characteristics 0 -10 -20 -30 -40 -50 -60 -70 -80 -90 -100 0.01 (2.5V product Except where noted therwise, Ta=25°C, VIN=VO+2V, VCONT=VIN, CIN=1.0µF, CO=1.0µF) Ripple Rejection Ripple Rejection RR (dB) Output Noise Output Noise Vn (µVrms) 200 150 100 50 0 1 10 100 1000 10000 RL=12Ω CN=0µF CN=470pF CN=0.01µF 0.1 1 10 100 1000 Frequency (kHz) Noise Reduction Capacitor CN (pF) Current Limit Characteristics 3.0 GND Pin Current 60 GND Pin Current (mA) 0 100 200 300 400 500 600 700 Output Voltage VO (V) 2.5 2.0 1.5 1.0 0.5 0.0 50 40 30 20 10 0 0 100 200 300 400 500 Output Current IOUT (mA) Output Current IOUT (mA) ESR Stability Area 10 Instable area Power Dissipation 1000 800 192 142 1.2mm On board Copper plane 80% Pd (mW) ESR (Ω) 1 Stable area 0.1 600 400 200 Not attached 0.01 0 100 200 300 400 0 0 50 100 150 200 Output Current IOUT (mA) Ambient Temperature Ta (ºC) MITSUMI Low-Saturation 300mA Regulators MM159X Series Characteristics 2 (1.8V, 5.0V product Except where noted therwise, Ta=25°C, VIN=VO+2V, VCONT=VIN, CIN=1.0µF, CO=1.0µF) Load Regulation(VO=1.8V) Output Voltage VO (V) Load Regulation(VO=5.0V) 5.2 Output Voltage VO (V) 0 100 200 300 400 500 600 1.9 1.8 1.7 1.6 1.5 5.1 5 4.9 4.8 4.7 0 100 200 300 400 500 600 Output Current IOUT (mA) Output Current IOUT (mA) Output Voltage(VO=1.8V) Output Voltage VOUT (V) 2.0 1.9 1.8 1.7 1.6 1.5 -50 -25 Output Voltage(VO=5.0V) Output Voltage VOUT (V) 5.2 5.1 5.0 4.9 4.8 4.7 -50 -25 0 25 50 75 100 125 150 0 25 50 75 100 125 150 Ambient Temperature Ta (ºC) Ambient Temperature Ta (ºC)
