LM1086CS-5.0/NOPB – TEXAS INSTRUMENTS

The LM1086CS-5.0/NOPB is a 5.0V, 1.5A low-dropout (LDO) voltage regulator in a SOT-23-5 (5-lead surface mount) package, featuring a lead-free, RoHS-compliant construction denoted by the “/NOPB” suffix. Unlike its higher-current siblings, this specific part is optimized for lower-power applications requiring a precisely regulated 5V output. Its input voltage range spans 6V to 15V, offering flexibility in system design. The quiescent current is typically under 5mA, minimizing power waste in battery-powered systems._x000D_

Key features include thermal shutdown protection, short-circuit protection, and input reverse-polarity protection. The LM1086CS-5.0/NOPB’s low dropout voltage (typically 0.5V at 1A) makes it ideal for applications where minimizing voltage loss between input and output is critical, such as portable devices or systems with limited input voltage headroom. Its small form factor and surface-mount packaging contribute to compact PCB designs. While not designed for high-current applications, this device excels in providing a stable, clean 5V rail for microcontrollers, sensors, and other low-power peripherals where precise voltage regulation is paramount. The absence of external components in many applications simplifies design and reduces board space.
