TS79M00 Series Taiwan Semiconductor 3-Termal 500mA Negative Voltage Regulator DESCRIPTION FEATURES The TS79M00 series of fixed output negative voltage Output Voltage: -5 & -12V regulators are intended as complements to the popular Output current up to 0.5A TS78M00 series device. These negative regulators are No external components required available in the same seven-voltage options as the Internal thermal overload protection TS7900 devices. In addition, one extra voltage option Internal short-circuit current limiting commonly employed in MECL systems is also available Output transistor safe-area compensation Output voltage offered in 4% tolerance in the negative TS79M00 Series. Available in fixed Compliant to RoHS Directive 2011/65/EU and output voltage options from -5.0 and -12 volts, these WEEE 2002/96/EC regulators employ current limiting, thermal shutdown, Halogen-free according to IEC 61249-2-21 and safe-area compensation--making them remarkably rugged under most operating conditions. With adequate APPLICATION heat sinking they can deliver output currents in excess Switching power supply of 0.5 ampere. Home appliance TO-252 Pin Definition: TO-220 (DPAK) 1. Ground 2. Input (tab) 3. Output Notes: MSL 3 (Moisture Sensitivity Level) per J-STD-020 TYPICAL APPLICATION CIRCUIT A common ground is required between the input and the output voltages. The input voltage must remain typically 2V above the output voltage even during the low point on the Input ripple voltage. XX = these two digits of the type number indicate voltage. * = C s required if regulator is located an appreciable distance from power supply filter. IN i ** = C is not needed for stability however, it does improve transient response.
