The SPX2930N-3.5 is a 3A low dropout (LDO) voltage regulator from Sipex Corporation. This regulator is designed to provide a stable and accurate output voltage even when the input voltage is close to the output voltage. Its low dropout voltage characteristic makes it ideal for battery-powered systems and other applications where voltage headroom is limited. The 3.5 in the part number indicates a fixed output voltage of 3.5V.

Applications:

• Battery-powered systems
• Post regulation for switching supplies
• Microprocessor power supplies
• Industrial power supplies
• Portable electronics

Features:

• 3A output current capability
• Low dropout voltage (typically 300mV at 3A)
• Fixed output voltage of 3.5V
• Overcurrent and overtemperature protection
• Reverse battery protection
• Short circuit protection
• Available in TO-220 and other packages

Benefits:

• Efficient power conversion due to low dropout voltage, extending battery life.
• Stable and accurate output voltage ensures reliable operation of downstream components.
• Robust protection features prevent damage to the regulator and the load.
• Simplified system design with minimal external components required.
• Wide operating temperature range allows for use in various environments.

Additional Details:

The SPX2930N-3.5 is a highly efficient LDO regulator that provides a stable 3.5V output. It includes internal protection circuitry to prevent damage from overcurrent, overtemperature, reverse battery conditions, and short circuits. The low dropout voltage ensures that the regulator can maintain a stable output even when the input voltage is only slightly higher than the output voltage. This is especially important in battery-powered applications where the battery voltage decreases as it discharges. The SPX2930N-3.5 is available in several package options. The regulator is designed for applications requiring a regulated 3.5V supply at currents up to 3A.
