The LT1761ES5-3.3TRPBF is a micropower, low noise, low dropout linear voltage regulator from Analog Devices, part of the LT1761 series. It provides a fixed 3.3V output voltage and can supply up to 100mA of output current with a low dropout voltage of 300mV at 100mA.
Designed for battery-powered systems, this regulator features a low quiescent current of 20μA, which drops to less than 0.1μA in shutdown mode. The output noise is as low as 20μVRMS over a 10Hz to 100kHz bandwidth when using an external bypass capacitor. It is stable with output capacitors as low as 1μF, including ceramic types, without requiring series resistance.
Internal protection circuitry includes reverse battery protection, current limiting, and thermal limiting. The LT1761ES5-3.3TRPBF is available in a compact 5-lead TSOT-23 package, making it suitable for space-constrained designs. Its wide input voltage range of 1.8V to 20V adds to its versatility.
Applications include cellular phones, pagers, battery-powered systems, frequency synthesizers, and wireless modems where low power consumption and low noise are critical.
