TS79L05CY Taiwan Semiconductor 3-Terminal 100mA Negative Voltage Regulator DESCRIPTION FEATURES Output Voltage Range -5V The TS79L05CY of negative voltage regulators are Output current up to 100mA inexpensive, easy-to-use devices suitable for a Internal thermal overload protection multitude of applications that require a regulated supply Internal short-circuit current limiting of up to 100mA. Like their higher power TS7905 and Output transistor safe-area compensation TS79M05 Series cousins, these regulators feature Output voltage offered in 4% tolerance internal current limiting and thermal shutdown making RoHS Compliant them remarkably rugged. No external components are Halogen-free according to IEC 61249-2-21 required with the TS79L05CY devices in many applications. These devices offer a substantial APPLICATION performance advantage over the traditional zener diode- Switching power supply resistor combination, as output impedance and Home appliance quiescent current are substantially reduced. SOT-89 Pin Definition: 1. Ground 2. Input 3. Output Notes: MSL 3 (Moisture Sensitivity Level) per J-STD-020 STANDARD APPLICATION CIRCUIT A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low point on the Input ripple voltage. XX = these two digits of the type number indicate voltage. * = Cin is required if regulator is located an appreciable distance from power supply filter. ** = Co is not needed for stability however, it does improve transient response. 1 Version: J2001 TS79L05CY Taiwan Semiconductor ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL LIMIT UNIT -35 V DC Input Voltage V IN P Internally Limited W Power Dissipation D o Operating Temperature range T 0 ~ +125 C OPR o 0 ~ +150 C Operating Junction Temperature Range T J o Storage Temperature Range T -65 ~ +150 C STG THERMAL PERFORMANCE PARAMETER SYMBOL TYP UNIT R C/W Junction to Case Thermal Resistance 18 JC 2 Notes: Considering 6cm of copper board heat-sink ELECTRICAL SPECIFICATIONS TS79L05CY o o (V =-10V, I =40mA, 0 C T 125 C, C =0.33F, C =0.1F, unless otherwise noted) IN OUT J IN OUT PARAMETER CONDITIONS SYMBOL MIN TYP MAX UNIT o T =25 C J -4.80 -5 -5.20 V Output voltage V -7.5VV -20V, OUT IN -4.75 -5 -5.25 V 5mAI 100mA OUT o -7.5VVin-20V Line Regulation T =25 C REG -- 50 150 mV J LINE 5mA I 100mA OUT -- 20 60 o Load Regulation T =25 C REG mV J LOAD 5mAI 40mA OUT -- 10 30 o Quiescent Current I =0, T =25 C I OUT J Q -- 3 6 mA -7.5VVin-25V -- -- 1.5 Quiescent Current Change I mA Q 5mAI 40mA OUT -- -- 0.1 o Output Noise Voltage 10Hzf 100kHz, T =25 C V J N -- 40 -- V Ripple Rejection Ratio f=120Hz, -8VVin-18V RR 41 49 -- dB o Voltage Drop I =100mA, T =25 C V OUT J DROP -- 1.7 -- V o Peak Output Current T =25 C Io peak -- 0.15 -- A J Temperature Coefficient of o o o I =5mA, 0 C T 125 C V / T -- -0.65 -- mV/ C OUT J OUT J Output Voltage Note: 1.
