XRE-SMD-MCP1799T-5002H/TT-5V-80MA-SOT23

The XRE-SMD-MCP1799T-5002H/TT is a low-dropout linear voltage regulator designed for battery-powered and portable electronic applications requiring stable, regulated power supply. This component belongs to the MCP1799 family of regulators, which are widely used in consumer electronics, industrial instrumentation, and embedded systems where compact size and low quiescent current are essential design considerations. Linear voltage regulators like this device function by continuously adjusting an internal pass transistor to maintain a constant output voltage despite variations in input voltage or load current. The fixed 5V output rating makes this part suitable for powering standard digital logic, microcontroller peripherals, and analog sensor circuits that require regulated 5V supplies. The 80mA output current capability positions this regulator in the low-to-medium current range, making it ideal for applications with modest power demands rather than high-current loads. The SOT23 surface-mount package is one of the most common component packages in modern electronics manufacturing. This compact form factor allows the regulator to occupy minimal board space while remaining hand-solderable and compatible with standard automated assembly processes. The small package also makes it practical for space-constrained applications such as portable medical devices, wireless sensor nodes, and hand-held test equipment. The MCP1799 series regulators are known for featuring low dropout voltage characteristics, which means they can maintain regulation even when the input voltage is only slightly higher than the desired output voltage. This property is particularly valuable in battery-powered systems where maximizing usable battery capacity is important. Additionally, these regulators typically incorporate protection features such as current limiting and thermal shutdown to ensure reliable operation across varying environmental conditions. Engineers typically specify this exact part when designing systems that demand a balance of small physical size, low power consumption, and adequate output current for supporting multiple chips or circuits. The fixed 5V output eliminates design complexity associated with adjustable regulators, reducing required external components and simplifying circuit design. This makes the XRE-SMD-MCP1799T-5002H/TT particularly attractive for rapid prototyping and production designs where component count and board real estate optimization directly impact manufacturing cost and reliability. This regulator would be selected over alternatives when SOT23 packaging is preferred, fixed 5V regulation is required, and the 80mA output current specification matches application requirements. Its combination of compact size, stable performance, and established reliability record makes it a standard choice across various industrial and consumer electronics segments.
