LT3023EDD#TRPBF

LT®3023 is a dual, micropower, low noise, low dropout regulator. With an external 0.01μF bypass capacitor, output noise drops to 20μVRMS over a 10Hz to 100KHz bandwidth. Designed for use in battery-powered systems, the low 20μA quiescent current per channel makes it an ideal choice. In shutdown, quiescent current drops to less than 0.1μA. Shutdown control is independent for each channel, allowing for flexibility in power management. The device is capable of operating over an input voltage from 1.8V to 20V, and can supply 100mA of output current from each channel with a dropout voltage of 300mV. Quiescent current is well controlled in dropout. Small ceramic capacitors can be used without the series resistance required by other regulators. Internal protection circuitry includes reverse battery protection, current limiting, thermal limiting and reverse current protection. Typical applications are cellular phones, pagers, battery-powered systems, frequency synthesizers, wireless modems.

• Low noise: 20μVRMS (10Hz to 100KHz), low quiescent current: 20μA/channel
• Stable with 1μF output capacitor, stable with aluminium, tantalum or ceramic capacitors
• Reverse battery protected, no reverse current, no protection diodes needed
• Overcurrent and overtemperature protected
• Minimum input voltage is 1.8V typical (ILOAD=100mA, TA=25°C)
• Dropout voltage is 0.15V maximum (ILOAD=1mA)
• GND pin current (per channel) is 45μA (ILOAD=0mA, TA=25°C)
• 10-lead plastic DFN package
• Temperature rating range from –40°C to 125°C
