LP5951MF-1.3

The Texas Instruments LP5951MF-1.3 is a micropower, 150-mA, low-dropout CMOS voltage regulator. It operates with an input voltage range of 1.8 V to 5.5 V and provides a fixed output voltage of 1.3 V. The device features a low quiescent current of 29 µA typical and a low shutdown current of less than 1 nA typical.

Key electrical specifications include a maximum output current of 150 mA, a typical dropout voltage of 200 mV at 150 mA, and a PSRR of 32 dB at 100 KHz. The regulator also includes thermal overload and short-circuit protection features. It is designed for applications requiring stable voltage regulation with minimal power consumption.

The LP5951MF-1.3 is available in a compact SOT-23-5 package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C, making it suitable for various environmental conditions. The device also features a logic-controlled enable pin for power management.

This linear voltage regulator is ideal for battery-powered devices and other applications where low power consumption and stable voltage output are critical. Its small package size and robust protection features make it a versatile component for embedded systems.
