TEXAS INSTRUMENTS  REG104GA-3.3G4  固定电压稳压器, LDO, 2.1V至15V, 230mV压差, 3.3V输出, 1A输出, SOT-223-5

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 1.7mA at IOUT = 1A and drops to 0.5µA in not enabled mode. Unlike regulators with PNP pass devices, quiescent current remains relatively constant over load variations and under dropout conditions. On-chip trimming results in high output voltage accuracy. Accuracy is maintained over temperature, line and load variations. Key parameters are tested over the specified temperature range.
