The TPL720 series products are CMOS process low Iq linear regulators with enable control function. The TPL720 series products support maximum 400mA output current, with typically only 1.4 μA ultra-low quiescent current. TPL720 series products are stable with low-ESR small ceramic output capacitors from 2.2 μF to 10 μF.The TPL720 series products have fast response performance when load dynamic drop or raise, especially for the load dynamic from with some load. The TPL720 series products have current limit and thermal protection, which improves TPL720 series products with high reliability. The TPL720 series products have a fixed output voltage range from 1 V to 3.3 V with ±1% output voltage accuracy, line regulation and load regulation under room temperature. The TPL720 series products are guaranteed over the operating temperature range of −40°C to +85°C. The TPL720 series products are available in SOT23-3 package, SOT23-5 package,SOT89-3 package, and 1×1 DFN-4 package.
