LP5951MGX-3.3

The LP5951MGX-3.3 is a low dropout (LDO) linear voltage regulator from Texas Instruments. It is a high-precision device designed to work as a current limiter, allowing currents to flow while delivering a precise output voltage. The device features an adjustable output voltage range, low quiescent current, thermal shutdown and short-circuit protection. It also offers power-on reset support, reverse current protection and additional features.

The LP5951MGX-3.3 belongs to the PMIC – Voltage Regulators – Linear family of voltage regulators, and it is designed to work with an input voltage of 3.3V and deliver a steady output current of up to 150mA. It features an adjustable output voltage range of 1.22V to 3.6V, and it is available in a 5-pin, 6-pin and 8-pin SOT-223 package. It is also capable of supplying current in both over-current and reverse-current protection, and it also includes a thermal shutdown feature for added protection.

The LP5951MGX-3.3 linear voltage regulator operates with the help of a voltage reference that is connected directly to the regulator’s output voltage. When the output voltage rises above the reference voltage, the current flow is limited by the closed loop control circuit, thus protecting the device and the load from damage. The output voltage is further regulated and maintained by two resistive divider networks. The first divider network is used to set the output voltage, while the reference voltage is monitored by the second divider network. This ensures that the output voltage remains stable and accurate over various environmental conditions.

The LP5951MGX-3.3 linear voltage regulator is mainly used in applications such as battery-powered or energy harvesting systems requiring a low quiescent current and precise output voltage. It is also used in automotive systems, industrial systems, lighting, and consumer electronics applications. Due to its low quiescent current, high precision output and compact size, the LP5951MGX-3.3 linear voltage regulator is an excellent choice for a wide variety of applications.
