The LP5910-1.1BYKAT is Texas Instruments’ most recent product in regards to linear regulator technology.
The LP5910 is specifically a low-dropout (LDO) controller, optimized to supply up to 300 mA to your system with low noise (12 µVRMS) and high PSRR (output voltage range of 0.8-2.3 V, input voltage range of 1.3-3.3 V). It additionally has a built in reverse current protection circuit to ensure that the device functions when output voltage is greater than the input. These features make the L5910 ideal for RF and analog circuits, as well as in applications such as portable medical devices and VR.
