TCM853 General Description

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 0.5mA (typ) over temperature, 2mA (typ) for the TCM851.

*This is a stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to Absolute Maximum Rating Conditions for extended periods may affect device reliability.

**The output may be shorted to NEGOUT or GND if the package power dissipation is not exceeded. Typical short circuit current to GND is 50mA.
