Product Overview

The LTC1682CS8-5#PBF is a Doubler Charge-Pump with an internal low noise, low dropout (LDO) linear regulator. This part is designed to provide a low noise boosted supply voltage for powering noise sensitive devices such as high frequency VCOs in wireless applications. An internal doubler charge-pump converts a 1.8 to 4.4V input to a boosted output, while the internal LDO regulator converts the boosted voltage to a low noise regulated output. The adjustable version allows the user to set VOUT via external resistors connected to FB. The regulator is capable of supplying up to 50mA of output current. Shutdown reduces the supply current to <5µA, removes the load from VIN by disabling the regulator and discharges VOUT to ground through a 100R switch. The LTC1682 LDO regulator is stable with only 2µF on the output. Small ceramic capacitors can be used, reducing PC board area.
