The SPX8863M5-3.0 is a low-dropout (LDO) voltage regulator manufactured by Sipex Corporation (now part of Exar Corporation). It is designed to provide a stable and regulated 3.0V output voltage from a higher input voltage, even when the input voltage is close to the output voltage. This makes it ideal for battery-powered applications and other situations where efficiency and low voltage operation are critical.

Applications

• Battery-Powered Devices
• Portable Electronics
• Post-Regulation for Switching Power Supplies
• Microprocessor Core Voltage Regulation
• Wireless Communication Devices
• Handheld Instruments

Features

• Low Dropout Voltage: Typically less than 200mV at full load
• Fixed Output Voltage: 3.0V
• Low Quiescent Current: Typically a few microamperes
• Short-Circuit Protection
• Over-Temperature Protection
• SOT-23-5 Package: Small surface-mount package
• Stable with Ceramic Output Capacitors

Benefits

• Extends battery life due to low dropout voltage and low quiescent current.
• Provides a stable and regulated 3.0V output voltage for sensitive electronic components.
• Protects the regulator and the load from damage due to short circuits and over-temperature conditions.
• Small package size allows for compact designs.
• Simplified design and reduced component count due to stability with ceramic capacitors.

Technical Specifications

The SPX8863M5-3.0 is housed in a SOT-23-5 package. Its input voltage range is typically from 2.5V to 5.5V, and provides a fixed 3.0V output. The dropout voltage is typically less than 200mV at the rated output current. The quiescent current is very low, typically in the microampere range, which minimizes power consumption. It includes built-in short-circuit protection and over-temperature protection to prevent damage to the regulator and the load. The device is stable with ceramic output capacitors, eliminating the need for large and expensive tantalum capacitors. It operates over a wide temperature range, typically from -40°C to +85°C. Consult the manufacturer's datasheet for precise electrical characteristics, including maximum output current, line and load regulation, and transient response.
