The MIC5318-2.8YMTTR is a low dropout (LDO) regulator manufactured by Micrel, now Microchip Technology. This LDO is designed to provide a stable 2.8V output voltage from a higher input voltage, with a low quiescent current, making it suitable for battery-powered applications and other low-power devices.

Applications

• Battery-powered devices
• Portable electronics
• Wireless communication devices
• Microcontroller power supplies
• Sensor power supplies

Features

• Low dropout voltage.
• Low quiescent current.
• Stable with ceramic output capacitors.
• Overcurrent protection.
• Overtemperature protection.

Benefits

• Extended battery life.
• Stable and regulated output voltage.
• Protection against overloads and short circuits.
• Reduced noise and ripple in the power supply.
• Simplified circuit design.

Additional Details

The MIC5318-2.8YMTTR is typically packaged in a small surface-mount package, such as a Thin MLF® (Micro Lead Frame). Key specifications include the input voltage range, output current capability, dropout voltage at a given current, and quiescent current. The datasheet provides detailed information on these parameters, as well as the recommended operating conditions and thermal characteristics. The LDO is designed to be stable with ceramic output capacitors, which are commonly used in portable electronics due to their small size and low ESR (equivalent series resistance). The YMTTR suffix typically indicates the specific package and tape-and-reel configuration.
