GENERAL DESCRIPTION  
Fixed – 4.1V or Adjustable – 0.5V to – 9V Output  
at 5mA  
4.5V to 10V Input Voltage Range  
Low Output Voltage Ripple  
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  
4.5Vto10.0Vandhave5mAoutputcurrentcapability. 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  
0.5µA (typ) over temperature, 2µA (typ) for the TCM851.
