Linear & Switching Voltage Regulators

LM2936MPX-5.0 Description

The LM2936MPX-5.0 is a fixed-output, low-dropout (LDO) linear voltage regulator from Texas Instruments, designed to deliver a stable 5V output at up to 50mA of load current. With a wide input voltage range of up to 40V, this regulator is optimized for applications requiring robust performance in harsh environments. Its ultra-low quiescent current of 9 µA and dropout voltage of 0.4V @ 50mA make it highly efficient for battery-powered and energy-sensitive systems. The device is housed in a SOT-223-4 surface-mount package, ensuring compact PCB integration.

LM2936MPX-5.0 Features

• Low Quiescent Current: 9 µA minimizes power loss in standby modes.
• High Input Voltage Tolerance: Operates up to 40V, ideal for automotive and industrial applications.
• Low Dropout Voltage: 0.4V @ 50mA ensures efficient regulation even with marginal input voltage headroom.
• Robust Protection: Includes over-temperature, reverse polarity, and short-circuit protection for enhanced reliability.
• Excellent PSRR: 60dB (120Hz) suppresses input noise, ensuring clean output voltage.
• Surface-Mount Packaging: SOT-223-4 for space-constrained designs.
• REACH Unaffected: Compliant with environmental regulations.

LM2936MPX-5.0 Applications

• Automotive Systems: Suitable for infotainment, sensors, and ECU power management due to high input voltage tolerance.
• Industrial Controls: Ideal for PLCs, instrumentation, and low-power actuators requiring stable voltage under varying loads.
• Battery-Powered Devices: Extends battery life in portable electronics, IoT sensors, and wearables thanks to ultra-low Iq.
• Embedded Systems: Provides reliable power for microcontrollers, FPGAs, and peripherals in harsh environments.

Conclusion of LM2936MPX-5.0

The LM2936MPX-5.0 stands out as a high-performance LDO regulator, combining low power consumption, high input voltage capability, and robust protection features. While marked as obsolete, its technical merits—such as 60dB PSRR and 9 µA Iq—make it a compelling choice for legacy designs or applications demanding reliability in extreme conditions. Its suitability for automotive, industrial, and portable electronics underscores its versatility, though designers should consider newer alternatives for future-proofing.
