Linear Technology LT3570
the LT3570 ideal for a wide variety of applications. The LT3570 features a programmable soft-start function that limits the feedback voltage during start-up helping prevent overshoot and limiting inrush current. The LDO controller is capable of delivering up to 10mA of base current to an external NPN transistor.- Min Voltage : 2.5V
- Max Voltage : 36V
- Max Operating Temp : 125°C
- Min Operating Temp : -40°C
