NCP630

NCP630 Linear Voltage Regulators Fast 3.0 A The NCP630 is a low dropout positive voltage regulator that is capable of providing a guaranteed output current of 3.0 A with a maximum dropout voltage of 1.25 V at 3.0 A over temperature. The fast turn on time allows step changes in loads commonly found in low voltage microprocessor applications. The NCP630 is currently offered as an adjustable output version that can be programmed down to 1.2 V with two external resistors and as a fixed output version at 3.47 V. On chip trimming adjusts the reference/output voltage to within "1.5% accuracy. Internal protection features consist of output current limiting and thermal shutdown. NCP630 is available in D2PAK package. Features Output Current of 3.0 A 1.25 V Maximum Dropout Voltage at 3.0 A Over Temperature Voltage on Shutdown Pin is TTL Compatible Reference/Output Voltage Trimmed to "1.5% Current Limit Protection Thermal Shutdown Protection −40°C to 125°C Junction Temperature Range Pb−Free Packages are Available Applications Microprocessor Power Supplies DSP Power Supplies SMPS Post Regulation Battery Chargers http://onsemi.com MARKING DIAGRAM 1 5 D2PAK D2T SUFFIX CASE 936A NC P630xD2T AWLYWWG NCP630A Tab = Ground Pin 1.
