TS78M00 Series Taiwan Semiconductor 3-Terminal 500mA Positive Voltage Regulator DESCRIPTION FEATURES The TS78M00 Series positive voltage regulators are Output Voltage Range 5V & 12V identical to the popular TS7800 Series devices, except Output current up to 500mA that they are specified for only half the output current. No external components required Like the TS7800 devices, the TS78M00 Series 3- Internal thermal overload protection Terminal regulators are intended for local, on-card Internal short-circuit current limiting voltage regulation. Internal current limiting, thermal Output transistor safe-area compensation Output voltage offered in 4% tolerance shutdown circuitry and safe-area compensation for the Compliant to RoHS Directive 2011/65/EU and internal pass transistor combine to make these devices WEEE 2002/96/EC remarkably rugged under most operating conditions. Halogen-free according to IEC 61249-2-21 Maximum output current with adequate heatsink is 500mA APPLICATION Switching power supply Home appliance TO-252 (DPAK) Pin Definition: 1. Input 2. Ground (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 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: F1512 Not Recommended TS78M00 Series Taiwan Semiconductor ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL LIMIT UNIT 35 V DC Input Voltage V IN P Internally Limited W Power Dissipation D o 0 ~ +150 C Operating Junction Temperature Range T J o T -65~+150 C Storage Temperature Range STG THERMAL PERFORMANCE PARAMETER SYMBOL LIMIT UNIT Junction to Case Thermal Resistance R 10 C/W JC R 100 C/W Junction to Ambient Thermal Resistance JA Notes: R is the sum of the junction-to-case and case-to-ambient thermal resistances.
