Description

The LT1761ES5-BYP is a low dropout (LDO) voltage regulator designed by Analog Devices. It is known for its ultra-low noise and high power supply rejection ratio (PSRR), making it suitable for powering sensitive RF and analog circuits. The device features a wide input voltage range of 1.6V to 20V and can output a fixed voltage of 1.2V, 1.5V, 1.8V, or adjustable options.
One of its key attributes is the low dropout voltage, typically around 200 mV at full load, allowing for efficient operation even with minimal headroom. The LT1761ES5-BYP also includes a bypass pin, enabling users to further reduce output noise by connecting an external capacitor. It has a maximum output current of 500 mA and offers thermal shutdown and current limiting for protection.
Its small footprint, available in a 5-lead SOT-23 package, makes it ideal for space-constrained applications. Overall, the LT1761ES5-BYP is a robust choice for applications requiring stable power supplies with low noise and high efficiency.
