NCP630 Linear Voltage Regulators - Fast 3.0 A The NCP630 is a low dropout positive voltage regulator that is NCP630 MAXIMUM RATINGS Rating Symbol Value Unit Input Voltage (Note 1) V 12 V in Shutdown Voltage Shutdown 0.3 to V + 0.3 V in Output Voltage V 0.3 to V + 0.3 V out in Output Short Circuit Duration (Note 2) Infinite Power Dissipation and Thermal Characteristics 2 Case 936F (D PAK) Power Dissipation (Note 2) P Internally Limited W D Thermal Resistance, JunctiontoAmbient R 45 C/W JA Thermal Resistance, JunctiontoCase R 5.0 C/W JC Operating Junction Temperature Range T 40 to 125 C J Storage Temperature Range T 55 to 150 C stg Lead Soldering Temperature 260C T 10 sec solder Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. This device series contains ESD protection and exceeds the following tests: Human Body Model JESD 22A114B Machine Model JESD 22A115A 2. The maximum package power dissipation is: T T J(max) A P D R JA PIN FUNCTION DESCRIPTION Pin No. NCP630A NCP630G Description 1 Shutdown Shutdown This input is used to place the NCP630 into shutdown mode. The NCP630 is active when a voltage greater than 2.0 V is applied. The NCP630 will be placed into a shutdown mode when a voltage less than 0.8 V is applied. If left unused then connect the pin high. 2 V V Positive power supply input voltage in in 3, Tab Ground Ground Power supply ground 4 V V Regulated output voltage out out 5 Adj This pin is to be Connected to the R resistors on the output. It main- sense tains 1.216 V between itself and ground. Refer to Figure 1 for equation. 5 Sense This pin is to be connected near the load for better regulation.
