DESCRIPTION

The TPS7A3001 is a negative, high-voltage (

capable of sourcing a maximum load of 200mA.

These linear regulators include a CMOS logic-level-compatible enable pin and capacitor-programmable soft-start

function that allows for customized power-management schemes. Other features available include built-in current

limit and thermal shutdown protection to safeguard the device and system during fault conditions.

The TPS7A3001 is designed using bipolar technology, and is ideal for high-accuracy, high-precision

instrumentation applications where clean voltage rails are critical to maximize system performance. This design

makes

it

an

excellent

choice

to

power

operational

amplifiers,

analog-to-digital

converters

(ADCs),

digital-to-analog converters (DACs), and other high-performance analog circuitry.
