Overview

The TPS7A30 series of devices are negative, highvoltage (-35 V), ultralow-noise (15.1 μ VRMS, 72-dB PSRR) linear regulators that can source a maximum load of 200 mA.

These linear regulators include a CMOS logic-levelcompatible enable pin and capacitor-programmable soft-start function that allows for customized powermanagement schemes. Other features include built-in current limit and thermal shutdown protection to safeguard the device and system during fault conditions.

The TPS7A30 family is designed using bipolar technology, and is ideal for high-accuracy, highprecision instrumentation applications where clean voltage rails are critical to maximize system performance. This design makes the device an excellent choice to power operational amplifiers, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other high-performance analog circuitry.

In addition, the TPS7A30 family of linear regulators is suitable for post dc-dc converter regulation. By filtering out the output voltage ripple inherent to dc-dc switching conversion, maximum system performance is provided in sensitive instrumentation, test and measurement, audio, and RF applications.

For applications that require positive and negative high-performance rails, consider TI's TPS7A49 family of positive high-voltage, ultralow-noise linear regulators.

Pin Configuration

Pin	Name	Type	Description
1	OUT	O	Regulator output. A capacitor ≥ 2.2 μF must be tied from this pin to ground to ensure stability.
2	FB	I	This pin is the feedback pin that sets the output voltage of the device.
3	NC	-	Not internally connected. This pin must either be left open or tied to GND.
4	GND	-	Ground
5	EN	I	This pin turns the regulator on or off. If V EN ≥ V EN(+HI, min) or V EN ≤ V EN(-HI, max) , the regulator is enabled. If V EN(+LO, max) ≥ V EN ≥ V EN(-LO, min) , the regulator is disabled. The EN pin can be connected to IN, if not used.
6	NR/SS	-	Noise reduction pin. Connecting an external capacitor to this pin filters the noise generated by the internal band gap. This capacitor allows RMS noise to be reduced to very low levels and also controls the soft-start function.
7	DNC	-	Do not connect. Do not route this pin to any electrical net, not even GND or IN.
8	IN	I	Input supply
