    The TCM850/1/2/3 combines an inverting charge pump and a low noise linear regulator in a single small outline package. They are ideal for biasing GaAS FETs in cellular telephone transmitter power amplifiers All four devices accept a range of input voltages from 4.5V to 10.0V and have 5mA output current capability. The TCM850/1/2 have both preset ( 4.1V) and variable ( 0.5V to 9.0V) output voltages that program with an external resistor divider. The TCM853 output voltage programs with an external positive control voltage. The TCM850/1/3 can be shutdown reducing quiescent current to less than 0.5A (typ) over temperature, 2A (typ) for the TCM851.  |
