Linear voltage regulators (LDOs) are components with a wide range of applications. They allow designers to adjust the output voltage of a power supply without adjusting the input voltage from the supply side. This has enabled designers to better control the power supply levels for their designs, ultimately resulting in improved power efficiency and more reliable designs. The SPX29300T-L-5-0/TR voltage regulator is a member of the SPX29XX Linear Voltage Regulator Family from Texas Instruments, and is a key component for a variety of applications.

The device offers low quiescent current of 80µA, an excellent line regulation of 0.2%/V, and –50dB PSRR at 1MHz.

Pin configurations on the SPX29300T-L-5-0/TR include a ground pin (GND) which should be connected to the power ground, an output voltage adjustment pin (VADJ), an enable pin (EN), a bypass pin (BY), a feedback pin (FB), and a supply voltage pin (VIN). The chip comes in an SOT- 223 package making it easily mountable in all types of boards.

How Does the SPX29300T-L-5-0/TR Voltage Regulator Operate?

The SPX29300T-L-5-0/TR linear voltage regulator works in three stages. Firstly, an internal detection circuitry monitors the output voltage level, and adjusts the voltage reference accordingly using the on-board voltage adjutment pin (VADJ) and the feedback pin (FB). Secondly, the device’s internal circuitry then uses this reference voltage, the enable pin (EN), the bypass pin (BY), and the ground pin (GND) in order to regulate the current from the supply voltage pin (VIN) and produce a stable output voltage. Lastly, the ground pin (GND) is used to connect to the power ground, allowing the device to provide a stable output voltage.
