TS7800 Series Taiwan Semiconductor 3-Terminal Fixed Positive Voltage Regulator DESCRIPTION FEATURES The TS7800 series voltage regulators are monolithic Output Voltage Range 5V, 8V, 9V, 12V, 24V integrated circuits designed as fixed-voltage regulators Output current up to 1A for a wide variety of applications including local, on-card No external components required regulation. These regulators employ internal current Internal thermal overload protection limiting,thermal shutdown, and safe-area compensation. Internal short-circuit current limiting With adequate heatsink they can deliver output currents Output transistor safe-area compensation up to 1 ampere. Although designed primarily as a fixed Output voltage offered in 4% tolerance voltage regulator, these devices can be used with Compliant to RoHS Directive 2011/65/EU and in external components to obtain adjustable voltages and accordance to WEEE 2002/96/EC. currents. Halogen-free according to IEC 61249-2-21 APPLICATION Power supply Home appliance TO-220 Pin Definition: 1. Input 2. Ground (tab) 3. Output TYPICAL 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. * = C is required if regulator is located an appreciable IN distance from power supply filter. ** = C is not needed for stability however, it does improve transient response.
