The LT1761ES5-1.8#TRMCT-ND is a high-performance, low dropout linear regulator (LDO) from Linear Technology, designed to deliver a well-regulated 1.8V output. This component is ideal for space-constrained and noise-sensitive applications, thanks to its small SOT-23 footprint and excellent noise characteristics.

With an input voltage range from 1.8V to 20V, the LT1761 can be used in a variety of systems, including those powered by multi-cell batteries or industrial supplies. It is capable of providing up to 100mA of output current, which makes it suitable for powering low-power devices such as microcontrollers, sensors, and RF circuits.

The LT1761ES5-1.8#TRMCT-ND boasts a low dropout voltage, typically just 300mV at full load, ensuring efficient operation even when the input voltage is close to the output voltage. This characteristic is particularly beneficial in battery-powered applications, where maximizing battery life is a priority.

Noise reduction is a key feature of this LDO, with a low output noise of only 20µV RMS over a 10Hz to 100kHz bandwidth when used with an optional bypass capacitor. This makes the LT1761 an excellent choice for precision analog circuits, where power supply noise can impact overall performance.

Additionally, the LT1761 includes several protective features to ensure long-term reliability. It has built-in thermal shutdown to prevent damage from overheating, as well as current limiting to protect against overcurrent conditions. The device also features reverse battery protection, which safeguards the regulator and the powered circuit in case of incorrect battery installation.

The LT1761ES5-1.8#TRMCT-ND is available in a tape and reel package, making it suitable for automated assembly processes, and is denoted by the "TRMCT-ND" suffix. This product is an excellent choice for designers looking for a compact, reliable, and low-noise power solution.
