The LT4356IS-3#TRPBF with Surge Suppressors Overvoltage Protection Regulator with Latchoff is a high accuracy, high speed, rail-to-rail low quiescent current, synchronous step-down regulator manufactured by Analog Devices. It integrates surge suppressors, overvoltage protection, low current consumption, output voltage, overcurrent and short-circuit protection, and thermal protection all in one device. The LT4356IS-3#TRPBF also features high efficiency, cruise mode operation, and fast transient response. The device has an input voltage range of 3.0V to 42V and can deliver up to 2A output current. The regulation voltage accuracy is ±1.5% over the entire operating temperature range. The device can also operate in pulse-skipping or fixed frequency, fixed-frequency dither and pulse-by-pulse current limiting.
