Texas Instruments Voltage Regulators - Linear LP2981-30DBVT

The LP2981-30DBVT is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output voltage with a maximum output current of 100 mA. It features an output tolerance of ¬±0.75% for A-grade devices and ¬±1.25% for standard grade. The regulator exhibits an ultra-low dropout voltage of approximately 200 mV at full load and 7 mV at light load, making it suitable for battery-powered applications. The typical quiescent current is 600 ¬µA, and it includes a shutdown feature that reduces current consumption to 0.01 ¬µA. The device operates over a temperature range of -40¬8C to 125¬8C and incorporates overcurrent and thermal protection for enhanced reliability. It is packaged in a compact SOT-23-5 form factor, making it ideal for space-constrained designs in applications such as smart meters, motor control, and portable electronics.
