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 Compliant to RoHS Directive 2011/65/EU and WEEE 2002/96/EC Halogen-free according to IEC 61249-2-21 shutdown circuitry and safe-area compensation for the internal pass transistor combine to make these devices remarkably rugged under most operating conditions. Maximum output current with adequate heatsink is 500mA ● APPLICATION ● Switching power supply ● Home appliance Pin Definition: 1. Input 2. Ground (Tab) 3. Output TO-252 (DPAK) 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 TS78M00 Series Taiwan Semiconductor ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL LIMIT UNIT DC Input Voltage VIN 35 V Power Dissipation PD Internally Limited W Operating Junction Temperature Range TJ 0 ~ +150 o TSTG -65~+150 o SYMBOL LIMIT UNIT Junction to Case Thermal Resistance RӨJC 10 °C/W Junction to Ambient Thermal Resistance RӨJA 100 °C/W Storage Temperature Range C C THERMAL PERFORMANCE PARAMETER Notes: RӨJA is the sum of the junction-to-case and case-to-ambient thermal resistances. The case thermal reference is defined at the solder mounting surface of the drain pins. RӨJA is guaranteed by design while RӨCA is determined by the user’s board design. RӨJA shown below for single device operation on FR-4 PCB in still air.
