TCM851 Description
The TCM850/1/2/3 bines 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...
