LM2776DBVR TI Charge Pump | SOT-23-6 | 2.7V-5.5V Input, 250mA Output

Product Overview

The LM2776DBVR is a high-performance switched capacitor voltage inverter from Texas Instruments (TI), designed to generate a regulated negative output voltage from a positive input voltage. Housed in a compact SOT-23-6 package, this device is ideal for space-constrained applications requiring a low-noise, efficient negative rail. With an input voltage range of 2.7V to 5.5V and output current capability up to 250mA, the LM2776DBVR provides a simple and cost-effective solution for generating negative voltages without the need for inductors.
