LT3066EDE#PBF

LT®3066 series is a micropower, low noise, low dropout voltage (LDO) linear regulator that operate over a 1.6V 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. This 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. Typical applications are battery-powered systems, automotive power supplies, industrial power supplies, avionic power supplies, portable instruments.

• Features an NMOS pull-down that discharges the output if active-low SHDN or IN is driven low
• Power good flag, input filtering for high PSRR
• Output tolerance is ±2% over line, load and temperature
• Stable with low ESR, ceramic output capacitors (3.3µF minimum)
• Single capacitor soft-starts reference and lowers output noise
• ADJ pin voltage range from 594 to 606mV (VIN=2.2V, ILOAD=1mA)
• Dropout Voltage, VIN=VOUT(nominal) is 150mV max (ILOAD=10mA)
• Quiescent current in shutdown is 3µA max (VIN=45V, V active-low SHDN=0V)
• Output voltage noise is 90µVRMS typ (COUT=10µF, ILOAD=500mA, VOUT=600mV, BW=10Hz to 100KHz)
• 12-lead plastic DFN package, -40°C to 125°C temperature rating
