The SE8117T15-HF-1.5V is a low dropout (LDO) linear regulator manufactured by Seaward Electronics Inc. This regulator is designed to provide a stable 1.5V output voltage from a higher input voltage, with low dropout voltage and low quiescent current. It is particularly well-suited for battery-powered applications and other systems where efficiency and low power consumption are critical.

Applications

• Battery-powered devices
• Portable electronics
• Microcontroller power supplies
• Post-regulation for switching power supplies
• Low-noise applications

Features

• Fixed 1.5V output voltage
• Low dropout voltage
• Low quiescent current
• Overcurrent protection
• Thermal shutdown protection
• Small package size

Benefits

• Extended battery life due to low quiescent current, minimizing power consumption in standby mode.
• Stable output voltage even with low input voltage, thanks to the low dropout voltage.
• Reliable operation due to overcurrent and thermal shutdown protection.
• Space savings on the PCB due to the small package size.
• Simplified design due to the fixed output voltage.

Additional Details

The SE8117T15-HF-1.5V has a typical dropout voltage of around 0.2V at its rated current. Its low quiescent current minimizes power consumption when the device is not actively regulating. The overcurrent protection limits the output current to prevent damage in case of a short circuit or overload. The thermal shutdown protection shuts down the device if the temperature exceeds a safe limit. The regulator is available in a small surface mount package, suitable for space-constrained applications. It is also RoHS compliant, ensuring environmental friendliness.
