The LM2936BMX-3.0 is a low dropout (LDO) voltage regulator from Texas Instruments (formerly National Semiconductor). It's designed to provide a stable 3.0V output with very low quiescent current, making it ideal for battery-powered applications and other systems where power efficiency is critical.

Applications

• Battery-powered systems: Used in portable devices, wearables, and other battery-operated equipment.
• Automotive applications: Employed in automotive electronics for stable voltage regulation.
• Microcontroller power supplies: Provides regulated power for microcontrollers in embedded systems.
• Memory backup circuits: Used in systems where continuous power is needed for memory retention.
• Industrial control systems: Utilized in industrial equipment requiring stable power supplies.

Features

• Low dropout voltage: Operates with a very small difference between input and output voltage.
• Low quiescent current: Minimizes power consumption in standby mode.
• Output current limiting: Protects the regulator and the load from overcurrent conditions.
• Reverse battery protection: Prevents damage from incorrect battery polarity.
• Thermal shutdown: Shuts down the regulator in case of overheating.

Benefits

• Extended battery life: Reduces power consumption, leading to longer battery life in portable devices.
• Stable output voltage: Provides a consistent voltage supply for sensitive electronic components.
• Robust protection: Protects against overcurrent, reverse polarity, and thermal overload.
• Compact design: Available in a small package for space-constrained applications.
• Reliable performance: Ensures stable operation in a variety of operating conditions.

Additional Details

The LM2936BMX-3.0 is specified for an output voltage of 3.0V and can handle an input voltage range up to 40V. The output current is typically around 50mA, suiting it to low-power applications. It comes in a small SOIC-8 package suitable for surface mounting. Its low quiescent current (typically 14µA) makes it ideal for applications requiring long standby times. The device also includes features like short-circuit protection and over-temperature protection to enhance system reliability.
