UTC 79DXX LINEAR INTEGRATED CIRCUIT 3 TERMINAL 0.5A NEGATIVE VOLTAGE REGULATOR DESCRIPTION The UTC 79DXX series of three-terminal negative regulators are available in TO-252 and TO-251 packages and with several fixed output voltage, making them useful in a wide range of application. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. 1 TO-252 FEATURES *Output current up to 0.5A *-5V; -6V;-8V;-12V;-15V;-18V;-24V output voltage available *Thermal overload protection *Short circuit protection 1 TO-251 1: GND 2: Input 3: Output BLOCK DIAGRAM GND R1 R2 OUTPUT Voltage reference Protection circuitry RSC UTC INPUT UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R101-012,D UTC 79DXX LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS (Ta=25°C) PARAMETER SYMBOL VALUE UNIT Input voltage (for Vo=–5 ~ –18V) Vi V R θ JA -35 -40 65 °C /W R θ JC 5 °C /W Topr Tstg 0 ~ +125 -65 ~ +150 °C °C (for Vo=–20 ~–24V) Thermal resistance junction-air Thermal resistance junction-cases Operating Temperature Storage Temperature UTC 79D05 ELECTRICAL CHARACTERISTICS (Refer to test circuits, 0<Tj<125°C,Io=500mA,Vi=-10V,Ci=33uF,Co=1uF, unless otherwise specified) PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT Output voltage Vo Line regulation ∆Vo Load regulation ∆Vo Quiescent current Quiescent current change IQ ∆IQ ∆Vo/∆T VN RR Vd Output voltage drift Output noise voltage Ripple rejection Dropout voltage Tj=25°C 5.0mA<Io<0.5A,Po<15W Vi=-7V to -20V Tj=25°C,Vi=-7V to -25V Tj=25°C,Vi=-8V to -12V Tj=25°C,Io=5.0mA to 0.5A Tj=25°C,Io=5.0mA to 200mA Tj=25°C Io=5mA to 0.5A Vi=-7V to -25V Io=5mA f=10Hz to 100kHz,Ta=25°C f=120Hz, Vi=-8V to -18V Io=1.0A,Tj=25°C -4.80 -5.0 -5.20 V 10 -5.25 100 V mV mV mV mV mA mA mA mV/°C µV dB V -4.75 54 10 3 4.3 0.05 0.1 -0.4 100 60 2 100 50 8 0.5 1.3 UTC 79D06 ELECTRICAL CHARACTERISTICS (Refer to test circuits, 0<Tj<125°C,Io=500mA,Vi=-11V,Ci=2.2uF,Co=1uF,unless otherwise specified) PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT Output voltage Vo Line regulation ∆Vo Load regulation ∆Vo Quiescent current Quiescent current change IQ ∆IQ Output voltage drift Output noise voltage Ripple rejection Dropout voltage UTC ∆Vo/∆T VN RR Vd Tj=25°C 5.0mA<Io<0.5A,Po<15W Vi=-8V to -21V Tj=25°C,Vi=-8V to -25V Tj=25°C,Vi=-9V to -13V Tj=25°C,Io=5.0mA to 0.5A Tj=25°C,Io=5.0mA to 200mA Tj=25°C Io=5mA to 0.5A Vi=-8V to -25V Io=5mA f=10Hz to 100kHz,Ta=25°C f=120Hz, Vi=-9V to -19V Io=0.5A, Tj=25°C -5.76 -6.0 -5.70 10 5 10 3 4.3 54 -6.24 V -6.30 120 60 120 60 8 0.5 1.3 V mV mV mV mV mA mA mA mV/°C µV dB V -0.5 130 60 2 UNISONIC TECHNOLOGIES CO., LTD. 2 QW-R101-012,D UTC 79DXX LINEAR INTEGRATED CIRCUIT UTC 79D08 ELECTRICAL CHARACTERISTICS (Refer to test circuits, 0<Tj<125°C,Io=500mA,Vi=-14V,Ci=2.2uF,Co=1uF,unless otherwise specified) PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT Output voltage Vo Line regulation ∆Vo Load regulation ∆Vo Quiescent current Quiescent current change IQ ∆IQ ∆Vo/∆T VN RR Vd Output voltage drift Output noise voltage Ripple rejection Dropout voltage Tj=25°C 5.0mA<Io<0.5A,Po<15W Vi=-10.5V to -23V Tj=25°C,Vi=-10.5V to -25V Tj=25°C,Vi=-11.5V to -17V Tj=25°C,Io=5.0mA to 0.5A Tj=25°C,Io=5.0mA to 200mA Tj=25°C Io=5mA to 0.5A Vi=-11.5V to -25V Io=5mA f=10Hz to 100kHz,Ta=25°C f=120Hz, Vi=-11.5V to -21.5V Io=0.5A,Tj=25°C -7.68 -8.0 -7.60 54 10 5 12 4 4.3 0.05 0.1 -0.6 175 60 2 -8.32 V -8.40 100 80 160 80 8 0.5 1.0 V mV mV mV mV mA mA mA mV/°C µV dB V UTC 79D09 ELECTRICAL CHARACTERISTICS (Refer to test circuits, 0<Tj<125°C,Io=500mA,Vi=-15V,Ci=2.2uF,Co=1uF,unless otherwise specified) PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT Output Voltage Vo Line regulation ∆Vo Load Regulation ∆Vo Quiescent Current Quiescent Current Change IQ ∆IQ Temperature coefficient of Vo Output Noise Voltage Ripple Rejection Dropout Voltage UTC ∆Vo/∆T VN RR Vd Tj=25°C -8.64 5.0mA<Io<0.5A,Po<15W -8.55 Vi =-11.5V to -
