Description
General part information
LT3066 Series
The LT3066 series are micropower, low noise, low dropout voltage (LDO) linear regulators that operate over a 1.8V to 45V input voltage range. The devices supply 500mA 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.A single external resistor programs the LT3066’s current limit, accurate to ±10% over a wide input voltage and temperature range. A PWRGD flag indicates output regulation.The LT3066 features an NMOS pull-down that discharges the output ifSHDNor IN is driven low.The LT3066 optimizes stability and transient response with low ESR ceramic capacitors, requiring a minimum of 3.3μF. Internal protection circuitry includes current limiting with foldback, thermal limiting, reverse battery protection, reverse current protection and reverse output protection.The LT3066 is available in fixed output voltages of 3.3V and 5V, and as an adjustable device with an output voltage range from 0.6V to 19V. The device is offered in the thermally-enhanced 12-lead 4mm × 3mm DFN and MSOP packages.ApplicationsBattery-Powered SystemsAutomotive Power SuppliesIndustrial Power SuppliesAvionic Power SuppliesPortable Instruments
