The LT3028IFE is a dual, micropower, low noise, low dropout regulator with independent inputs, designed by LT. It operates over a wide input voltage range of 1.8V to 20V. Output 1 can supply 500mA with a dropout voltage of 320mV, while Output 2 can supply 100mA with a dropout voltage of 300mV. The device boasts a low quiescent current of 30µA per output and a very low shutdown current of less than 0.1µA.
With an external 0.01µF bypass capacitor, the output noise is a low 20µVRMS over a 10Hz to 100kHz bandwidth. The LT3028IFE is stable with output capacitors as low as 1µF for the 100mA output and 3.3µF for the 500mA output, and can utilize ceramic capacitors without requiring series resistance. Internal protection includes reverse-battery protection, current limiting, and thermal limiting.
This regulator is available as an adjustable device with a 1.22V reference voltage. It is offered in a thermally enhanced 16-lead TSSOP and a 16-lead, low profile (5mm × 3mm) DFN package, suitable for surface mounting.
The LT3028IFE can supply 500mA from Output 1 and 100mA from Output 2.
The input voltage range for the LT3028IFE is from 1.8V to 20V.
The dropout voltage is 300mV at 100mA and 320mV at 500mA.
The quiescent current is 30µA per output.
