描述
The LT3028 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.
Internal protection circuitry includes reverse-battery protection, current limiting and thermal limiting protection. The device is available as an adjustable device with a 1.22V reference voltage. The LT3028 regulator is available in the thermally enhanced 16-lead TSSOP and 16-lead, low profile (5mm × 3mm × 0.75mm) DFN packages.
