FAN54110UCX

Battery Chargers Overview

The FAN54110UCX is a single-channel, low-dropout linear regulator manufactured by onsemi. It provides a fixed output voltage of 3.3V with a maximum continuous load current of 150mA. The device operates from an input voltage range of 2.7V to 5.5V. Key electrical specifications include a typical dropout voltage of 280mV at full load and a quiescent current of 16µA. It features thermal shutdown and reverse battery protection. The component is housed in a compact SOT-23-5 surface-mount package.

Battery Chargers Feature Summary

• Integrated reverse battery protection prevents damage from incorrect polarity connections.
• Thermal shutdown circuitry automatically reduces output current to protect the device during overheating conditions.
• Low quiescent current design extends battery life in portable applications.
• Fixed 3.3V output eliminates external resistor requirements for simplified board layout.

Battery Chargers Applications

• Portable consumer electronics requiring stable 3.3V logic supplies
• Battery-powered devices needing efficient power management
