LT3028IDHCPBF Description

Short technical summary and product information.

The LT3028IDHCPBF from Linear Technology is a dual-channel, micropower, low noise, and low dropout voltage regulator. It features independent inputs for each output, providing flexibility in power management.

 

Key electrical specifications include a wide input voltage range of 1.8V to 20V. Output 1 can deliver up to 500mA with a typical dropout voltage of 320mV, while Output 2 supports 100mA with a 300mV dropout voltage. The device exhibits very low output noise of 20µVRMS over a 10Hz to 100kHz bandwidth and a low quiescent current of 30µA per output. In shutdown mode, the quiescent current drops to less than 0.1µA.

 

The LT3028 is designed for battery-powered applications and is stable with output capacitors as low as 1µF for the 100mA output and 3.3µF for the 500mA output, including ceramic capacitors. Internal protection circuitry includes reverse-battery protection, current limiting, and thermal limiting.

 

This regulator is available in a thermally enhanced 16-lead DFN package with a 5mm x 3mm footprint, suitable for surface mounting. Its adjustable output capability ranges from 1.22V to 20V.
