The LT3011 is a high voltage micro-power, low dropout regulator that delivers up to 50mA of continuous output current with a low dropout voltage of only 300mV at full load. The IC features an input voltage range of 3V to 80V, delivering output voltages as low as 1.24V and up to 60V. The device’s Power Good delay flag is programmable and indicates output regulation. A single capacitor is used to program the delay between this regulated output level and the flag indication, providing greater flexibility when compared to a simple power-on reset. The 80V input voltage capability makes it ideal for 42V automotive applications, 48V telecom backup supplies and industrial control applications. Low quiescent current of 46µA (operating) and 1µA (in shutdown) make it an excellent choice for battery-powered “keep alive” systems that require optimum run time.
