Description

General part information

LTC1928-5 Series

The LTC1928-5 is a doubler charge pump with an internal low noise, low dropout (LDO) linear regulator. The part is designed to provide a low noise boosted supply voltage for powering noise sensitive devices such as high frequency VCOs in wireless applicationsAn 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 VINby disabling the regulator and discharges VOUTto ground through a 200Ω 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.ApplicationsVCO Power Supplies for Cellular Phones2-Way PagersWireless PCMCIA CardsPortable Medical InstrumentsLow Power Data AcquisitionRemote TransmittersWhite LED DriverGaAs Switches
