DESCRIPTION

· The TPS7A49 series are positive, high-voltage (36 V), ultralow-noise linear regulators capable of sourcing a 150-mA load.

· These regulators feature a CMOS logic-level-compatible enable pin and a capacitor-programmable soft-start function for customized power management.

· Built-in current limit and thermal shutdown protection safeguard the device and system during fault conditions.

· Designed using bipolar technology, they are ideal for high-accuracy, high-precision instrumentation applications.

· Suitable for post DC-DC converter regulation, they filter out output voltage ripple inherent to DC-DC switching conversion.
