LT1054IPE4 TI Switched Capacitor Voltage Converter | 8-PDIP | Input 3.5V-15V, Output -3.5V to -15V

Product Overview

The LT1054IPE4 from Texas Instruments is a monolithic, bipolar, switched-capacitor voltage converter that provides both positive-to-negative voltage conversion and voltage regulation. It operates over a wide input voltage range of 3.5V to 15V and delivers an output voltage of -3.5V to -15V with up to 100mA output current. The device is housed in an 8-pin PDIP package, making it suitable for through-hole PCB assembly. Its high efficiency (up to 90%) and low quiescent current (2.5mA typical) make it ideal for battery-powered and industrial applications.
