Power over Ethernet (PoE)
LED Lighting
Bias Power Supplies

The TPS7A4001 device is a very high voltagetolerant linear regulator that offers the benefits of a thermally-enhanced package (HVSSOP), and is able to withstand continuous DC or transient input voltages of up to 100 V.

The TPS7A4001 device is stable with any output capacitance greater than 4.7 μF and any input capacitance greater than 1 μF (over temperature and tolerance). Therefore, implementations of this device require minimal board space because of its miniaturized packaging (HVSSOP) and a potentially small output capacitor. In addition, the TPS7A4001 device offers an enable pin (EN) compatible with standard CMOS logic to enable a low-current shutdown mode.

The TPS7A4001 device has an internal thermal shutdown and current limiting to protect the system during fault conditions. The HVSSOP packages has an operating temperature range of TJ = -40°C to 125°C.

In addition, the TPS7A4001 device is ideal for generating a low-voltage supply from intermediate voltage rails in telecom and industrial applications; not only can it supply a well-regulated voltage rail, but it can also withstand and maintain regulation during very high and fast voltage transients. These features translate to simpler and more cost-effective electrical surge-protection circuitry for a wide range of applications, including PoE, bias supply, and LED lighting.

TPS7A4001 Pin Configuration

PIN - NAME	PIN - NO.	I/O	DESCRIPTION
OUT	1	O	Regulator output. A capacitor > 4.7 μF must be tied from this pin to ground to assure stability.
FB	2	O	This pin is the input to the control-loop error amplifier. It is used to set the output voltage of the device.
NC	3	-	Not internally connected. This pin must either be left open or tied to GND.
NC	6	-	Not internally connected. This pin must either be left open or tied to GND.
NC	7	-	Not internally connected. This pin must either be left open or tied to GND.
GND	4	-	Ground
EN	5	I	This pin turns the regulator on or off. If V EN ≥ V EN_HI the regulator is enabled. If V EN ≤ V EN_LO , the regulator is disabled. If not used, the EN pin can be connected to IN. Make sure that V EN ≤ V IN at all times.
IN	8	I	Input supply
PowerPAD	-	-	Solder to printed-circuit-board (PCB) to enhance thermal performance. NOTE: The PowerPAD is internally connected to GND. Although it can be left floating, TI highly recommends connecting the PowerPAD to the GND plane.
