LT3063 - 45V VIN, Micropower, Low Noise, 200mA LDO with Active Output Discharge
The LT®3063 is a micropower, low dropout (LDO) linear regulator that operates over a 1.6V to 45V supply range and is available in a series of fixed output and adjustable versions. The device supplies 200mA of output current with a typical dropout voltage of 300mV. A single external capacitor provides programmable low noise reference performance and output soft-start functionality. The LT3063’s quiescent current is merely 45μA and provides fast transient response with a minimum 3.3μF output capacitor. In shutdown, quiescent current is less than 3μA and the reference soft-start capacitor is reset.
The LT3063 features an NMOS pull-down that discharges the output if SHDN or IN is driven low.
Internal protection circuitry includes reverse-battery protection, reverse-current protection, current limit with foldback and thermal shutdown.
The LT3063 is available in fixed output voltages of 3.3V and 5V, and as an adjustable device with an output voltage range from the 600mV reference up to 19V. The LT3063 is offered in the thermally enhanced 8-lead 2mm × 3mm DFN and MSOP packages.
