FEATURES

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

4.5Vto10.0Vandhave–5mAoutputcurrentcapability. 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.
