NCV8509 Series Voltage Regulator - Sequenced Linear, Dual The NCV8509 Series are dual voltage regulators whose output voltages power up in such a manner as to protect the integrity of modern day microcontroller I/O and ESD input structures. Newer NCV8509 Series MAXIMUM RATINGS Rating Value Unit V (dc) 0.3 to 50 V IN1 V Peak Transient Voltage 50 V IN1 V (dc) 50 V IN2 V (Current out of pin) 10 mA IN2 Operating Voltage 50 V Input Voltage Range (SLEW, RESET, Delay) 0.3 to 10 V V 10 V OUT1 V 10 V OUT2 Electrostatic Discharge (Human Body Model) 4.0 kV (Machine Model) 400 V Package Thermal Resistance, SOW16 E Pad: JunctiontoCase, R 16 C/W JC JunctiontoAmbient, R 57 C/W JA Lead Temperature Soldering: Reflow: (SMD styles only) (Note 1) 240 peak (Note 2) C Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. 60 second maximum above 183C. 2. 5C/+0C allowable conditions.
