LT3028EDHC#PBF

LT3028 is a dual, micropower, low noise, low dropout regulator with independent inputs. Designed for use in battery-powered systems, the low 30µA quiescent current per output makes it an ideal choice. In shutdown, quiescent current drops to less than 0.1µA. Shutdown control is independent for each output, allowing for flexibility in power management. This device can supply 100mA of output current from output 2 with a dropout voltage of 300mV. Quiescent current is well controlled in dropout. This device regulator is stable with output capacitors as low as 1µF for the 100mA output and 3.3µF for the 500mA output. Small ceramic capacitors can be used without the series resistance required by other regulators. It is widely used in application such as cellular phones, pagers, battery-powered systems, frequency synthesizers, wireless modems, tracking/sequencing power supplies etc.

• Low noise is 20µVRMS typical (10Hz to 100KHz)
• Independent inputs, wide input voltage range is 1.8V to 20V
• Very low shutdown current is 0.1µA maximum
• Dropout voltage is 0.10V typical at (ILOAD = 1mA)
• Adjustable outputs from 1.22V to 20V
• Stable with aluminium, tantalum or ceramic capacitors
• Overcurrent and overtemperature protected
• Tracking/sequencing capability
• Operating junction temperature is -40°C to 125°C
• Package style is 16-lead plastic DFN
