Product Overview

The LT3028EFE#PBF is a dual micro-power low noise low-dropout Regulator with independent inputs. With an external 0.01µF bypass capacitor, output noise is a low 20µVRMS over a 10Hz to 100kHz bandwidth. 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. The device is capable of operating over an input voltage range of 1.8 to 20V. Output 1 can supply 500mA of output current with a dropout voltage of 320mV. The device can supply 100mA of output current from output 2 with a dropout voltage of 300mV. Quiescent current is well controlled in dropout. The 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.
  • Reverse battery protected
  • No protection diodes needed
  • Overcurrent and overtemperature protected
  • Tracking/sequencing capability

Applications
