The LTC1877EMS8#TRPBF is an integrated low-iq monostable synchronous switching voltage regulator designed and manufactured by Analog Devices. It has an operating input voltage range of 4.5 V to 40 V and an output voltage range of 0.3 V to 36 V. It has an adjustable switching frequency range of 150 KHz to 1.2 MHz, a peak operating current of 1.5 A, and a thermally-enhanced 5-pin 3x3 mm SOT-23-5 package. It features integrated low RDS(ON) synchronous rectifier to minimize power losses, integrated soft-start to reduce inrush current, and over temperature, over voltage, over current, and input under voltage protection for continuous and safe operation. It also includes pre-biased load and fast transient response enables quick operation and better loop stability. The device can be used for adaptive voltage scaling application, DC-DC converters, and other low-power, space-constrained applications.
