TEXAS INSTRUMENTS  REG113EA-3.3/250  固定电压稳压器, LDO, 1.8V至10V, 250mV压差, 3.3V输出, 400mA输出, VSSOP-8

The is a 3.3V fixed output low-noise low-dropout LDO Linear Regulator with low ground pin current. Its new DMOS topology provides significant improvement over previous designs, including low-dropout LDO voltage and better transient performance. In addition, no output capacitor is required for stability, unlike conventional low-dropout LDO regulators that are difficult to compensate and require expensive low ESR capacitors greater than 1µF. Typical ground pin current is only 850µA at IOUT = 400mA and drops to 10nA when not enabled. Unlike regulators with PNP pass devices, quiescent current remains relatively constant over load variations and under dropout conditions. Accuracy is maintained over temperature, line and load variations.
