Doubler Charge Pump With Low Noise Linear Regulator In ThinSOT

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 applications. An internal Charge Pump converts a 2.7V to 4.4V input to a boosted output, while the internal LDO Regulator con- verts 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 <8A, removes the load from VIN by disabling the Regulator and discharges VOUT to ground through a 200 Switch The LTC1928-5 LDO Regulator is stable with only 2F on the output. Small ceramic capacitors CAN be used, reduc- ing PC board area. By Linear Technology Corporation
