特点 Low Output Noise: 90μV RMS (100kHz BW) Low Profile (1mm) ThinSOT? PackageFixed Output Voltage: 5VInput Voltage Range: 2.7V to 4.4VUses Small Ceramic CapacitorsNo Inductors RequiredOutput Current Up to 30mA550kHz Switching FrequencyLow Operating Current: 190μALow Shutdown Current: 4μAInternal Thermal Shutdown and Current Limiting典型应用典型应用描述An internal charge pump converts a 2.7V to 4.4V input to a boosted output, while the internal LDO regulator converts the boosted voltage to a low noise regulated output. The regulator is capable of supplying up to 30mA of output current. Shutdown reduces the supply current to <8μA, removes the load from V IN by disabling the regulator and discharges V OUT to ground through a 200 Ohms switch.The LTC1928-5 LDO regulator is stable with only 2μF on the output. Small ceramic capacitors can be used, reducing PC board area.The LTC1928-5 is short-circuit and overtemperature protected. The part is available in a 6-pin low profile (1mm) ThinSOT package.
