LT1761ES5-1.2#TRPBF: Low-Noise, Low-Dropout Voltage Regulator

The LT1761ES5-1.2#TRPBF is a high-performance, low-dropout (LDO) voltage regulator from Linear Technology, now part of Analog Devices, which is renowned for its exceptional noise reduction capabilities and power supply stability. This regulator is designed to deliver a fixed output voltage of 1.2V, making it an ideal choice for precision applications where a consistent and clean power supply is crucial.

With an output current capability of up to 100mA, the LT1761 series is particularly suited for portable and battery-powered equipment where efficiency and battery life are of paramount importance. The device operates with a very low quiescent current of just 20µA, which further extends battery life, and has a low dropout voltage of only 300mV at full load, allowing for efficient operation even when the input-to-output differential is minimal.

The LT1761ES5-1.2#TRPBF boasts outstanding noise performance, with a low output noise of only 20µV_RMS over a 10Hz to 100kHz bandwidth, thanks to its internal noise reduction bypass capacitor. This feature makes it particularly well-suited for sensitive RF and audio applications that demand a clean power supply for optimal performance.

Additional features of this LDO include overcurrent and overtemperature protection, ensuring reliable operation under a wide range of conditions. The device is also stable with output capacitors as low as 1µF, which allows for the use of small, cost-effective capacitors with low equivalent series resistance (ESR).

The regulator is packaged in a compact SOT-23 form factor, designated by the 'ES5' in its part number, which is ideal for space-constrained applications. The '#TRPBF' suffix indicates that the product is provided in tape and reel packaging, suitable for automated assembly processes, and that it is RoHS compliant with a lead (Pb)-free finish.

In summary, the LT1761ES5-1.2#TRPBF is a versatile, high-performance LDO voltage regulator that offers low noise, low dropout, and high efficiency, making it an excellent choice for a wide range of applications including portable devices, wireless communications, and precision instrumentation.
