NOTES： （1） Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings Indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics. （2） Power Dissipation is kept in a safe range by current limiting circuitry, Refer to Overload Recovery in Application Notes. （3） The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD =（TJ(MAX - TA)/ θJA. All numbers apply for packages soldered directly into a PC board, Refer to Thermal Considerations in the Application Notes. （4） For testing purposes, ESD was applied using human body model, 1.5kΩ in series with 100pF. （5） Typical Values represent the most likely parametric norm. （6） All limits are guaranteed by testing or statistical analysis. （7） IFULL LOAD is defined in the current limit curves. The IFULL LOAD Curve defines the current limit as a function of input-to-output voltage. Note that 30W power dissipation for the CM1084 is only achievable over a limited range of input-to-output voltage. （8） Load and line regulation are measured at constant junction temperature, and are guaranteed up to the maximum power dissipation of 30W. Power dissipation is determined by the input/output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output rage. （9） Dropout voltage is specified over the full output current range of the device. （10） The minimum output current required to maintain regulation. 2004/10/13 Preliminary Rev. 1.1 Champion Microelectronic Corporation Page 5 CM1084 5.0 AMP POSITIVE VOLTAGE REGULATOR APPLICATION CIRCUIT Fixed Output Voltage Regulator Adjustable Regulator 2004/10/13 Preliminary Rev. 1.1 Champion Microelectronic Corporation Page 6 CM1084 5.0 AMP POSITIVE VOLTAGE REGULATOR PACKAGE DIMENSION TO-220 (N220) C B S T Q F A A B U C D F G H J K H Z L N Q R S T U V Z R J G L D V N TO-252 (N252) Y C B E L J D H G 2004/10/13 Preliminary A K L1 S L2 X R Rev. 1.1 Champion Microelectronic Corporation Page 7 CM1084 5.0 AMP POSITIVE VOLTAGE REGULATOR PACKAGE DIMENSION TO-263 (N263) C B K S A V E J G H D TO-263 (N263) C B K S A V E G J H D Side View Front View 2004/10/13 Preliminary Rev. 1.1 Champion Microelectronic Corporation Page 8 CM1084 5.0 AMP POSITIVE VOLTAGE REGULATOR IMPORTANT NOTICE Champion Microelectronic Corporation (CMC) reserves the right to make changes to its products or to discontinue any integrated circuit product or service without notice, and advises its customers to obtain the latest version of relevant information to verify, before placing orders, that the information being relied on is current.
