TPS76950DBVR

TPS76950DBVR is an adjustable, low-dropout (LDO), linear regulator that is capable of providing an output current of 150 mA. It has a wide input voltage range and offers an adjustable output voltage between 2.3 V and 12 V. The device is ideal for providing unregulated system power sources with an adjustable voltage, enabling the design of power converters with the flexibility of a variable voltage regulator.

The device consists of a low-power, PNP-type, N-channel MOSFET, which is used to provide a linear voltage source with an adjustable turn-on voltage. This voltage is determined by the potential difference between the gate of the MOSFET and the output voltage. The gate of the MOSFET is controlled using a voltage divider, which consists of a resolution resistor for adjusting the voltage reference and a compensation capacitor for reducing ripple in the output voltage. The output voltage is adjusted by applying an external voltage to the “adjust” pin, which changes the gate voltage. When the output voltage falls below a programmed cutoff value, the device transitions to the “regulation” state and the MOSFET is turned off. This prevents the output voltage from exceeding the programmed cutoff voltage.

The device has a low quiescent current of 3.5 µA, making it well suited for battery-powered applications. It also has a low dropout voltage of 85 mV and a high efficiency of 80%. It also offers short-circuit protection to protect the device in the event of an overload or unsafe conditions.

The TPS76950DBVR offers a wide variety of applications. It is ideal for providing regulated power to low-power analog, digital and RF circuits in portable, battery-powered systems. It can also be used to provide an adjustable power supply for memories, microprocessors and DSPs, or for powering LED drivers. Additionally, the device can be used in automotive and industrial applications such as in PTZ cameras, medical equipment and point-of-sale devices.
