Texas Instruments LM2931Z-5.0 Fixed LDO Voltage Regulator 5V 100mA TO-92

Texas Instruments LM2931Z-5.0 Fixed LDO Voltage Regulator provides a stable 5V fixed output with a maximum output current of 100mA. This low-dropout (LDO) linear voltage regulator is designed for applications where minimal power wastage is required, with an extremely low quiescent current of 1mA or less when driving 10mA loads.

Overview

The regulator has a typical dropout voltage of 300mV, which helps extend usable battery life by allowing regulation to continue as the input voltage approaches the output level. Its very low required input-output differential voltage makes it suitable for battery-powered and standby power systems where energy conservation is a priority. The product is supplied in a TO-92 package.

Key Protection Features

• Reverse Battery Protection: Fully protected against damage from reverse battery installation or two-battery jump-start scenarios.
• Load Dump Protection: Can automatically shut down during input voltage transients, such as load dumps, where the input may momentarily exceed the maximum rating.
• Mirror-Image Insertion Safety: Cannot be harmed by temporary reverse insertion.
• Standard Protections: Includes short-circuit and thermal overload protection.

Applications

Ideal for low-power applications, this LDO is commonly used in memory standby circuits, power supplies for CMOS and other low-power processors, and systems requiring up to 100mA of regulated 5V power. It is also suitable for automotive and general power management tasks.
