Ground These voltage regulators are monolithic integrated circuits designed CASE 936 3. Output 1 as fixed voltage regulators for a wide variety of applications 3 including local, oncard regulation. These regulators employ internal Heatsink surface (shown as terminal 4 in current limiting, thermal shutdown, and safearea compensation. With case outline drawing) is connected to Pin 2. adequate heatsinking they can deliver output currents in excess of 4 DPAK3 1.0 A. Although designed primarily as a fixed voltage regulator, these DT SUFFIX devices can be used with external components to obtain adjustable 2 1 CASE 369C voltages and currents. 3 Features STANDARD APPLICATION Output Current in Excess of 1.0 A No External Components Required Input MC78XX Output Internal Thermal Overload Protection C * in C ** O Internal Short Circuit Current Limiting 0.33 F Output Transistor SafeArea Compensation Output Voltage Offered in 1.5%, 2% and 4% Tolerance A common ground is required between the 2 input and the output voltages. The input voltage Available in Surface Mount D PAK3, DPAK3 and Standard must remain typically 2.0 V above the output 3Lead Transistor Packages voltage even during the low point on the input NCV Prefix for Automotive and Other Applications Requiring ripple voltage. Unique Site and Control Change Requirements AECQ100 XX, These two digits of the type number Qualified and PPAP Capable indicate nominal voltage. These are PbFree Devices * C is required if regulator is located an in appreciable distance from power supply filter. MAXIMUM RATINGS (T = 25C, unless otherwise noted) A ** C is not needed for stability however, O Value Unit it does improve transient response. Values of less than 0.1 F could cause instability. 369C 221A 936 Rating Symbol Input Voltage (5.0 18 V) V 35 Vdc I (24 V) 40 ORDERING INFORMATION See detailed ordering and shipping information in the package Power Dissipation P Internally Limited W D dimensions section on page 21 of this data sheet.
