Typical Application Circuit Note 3: Input Capacitor (CIN=1uF) is recommended in all applications. Note 4: Output Capacitor (COUT=1uF/6.8uF) is recommended in all applications to assure the stability of circuit. 1uF Tantalum capacitor or 6.8uF ceramic capacitor is recommended. ________________________________________________________________________ http://www.union-ic.com Rev.05 Dec.2013 6 / 10 UM142xx 14 13 12 11 10 9 8 7 6 5 4 3 2 Output Voltage VS Input Voltage Supply Current VS Input Voltage 5.10 5.05 5.00 Output Voltage(V) IS(uA) Typical Operating Characteristics 4.95 4.90 4.85 IO=150mA IO=10mA 4.80 4.75 5 6 7 8 9 10 11 4 5 6 7 12 8 9 10 11 12 13 Input Voltage(V) VDD(V) Output Voltage VS Temperature 5.10 600 Dropout Voltage(mV) Output Voltage(V) 5.08 5.06 5.04 5.02 5.00 IO=10mA 4.98 25 50 75 100 125 Temperature( C) 300 200 100 0 50 100 150 200 250 300 Ripple Rejections VS Frequency 80 VIN=6.0V 70 5.03 60 5.02 50 5.01 PSRR(dB) Output Voltage(V) 400 Output Current(mA) Output Voltage VS Output Current 5.04 500 0 O 5.05 Dropout Voltage VS Output Current 700 5.00 4.99 40 30 4.98 20 4.97 10 Iload=3mA 4.96 0 4.95 1000 0 50 100 150 200 250 300 10000 100000 Frequency(Hz) Output Current(mA) ________________________________________________________________________ http://www.union-ic.com Rev.05 Dec.2013 7 / 10 UM142xx Package Information UM142xxS: SOT23-3 Outline Drawing Symbol A A1 A2 b c D E E1 e e1 L L1 θ DIMENSIONS MILLIMETERS Min Max 1.050 1.250 0.000 0.100 1.050 1.150 0.300 0.500 0.100 0.200 2.820 3.020 1.500 1.700 2.650 2.950 0.950REF 1.800 2.000 0.550REF 0.300 0.600 0° 8° INCHES Min Max 0.041 0.049 0.000 0.004 0.041 0.045 0.012 0.020 0.004 0.008 0.111 0.119 0.059 0.067 0.104 0.116 0.037REF 0.071 0.079 0.022REF 0.012 0.024 0° 8° Land Pattern NOTES: 1.
