LT1761ES5-3.3 – LINEAR TECH

The Linear Technology LT1761ES5-3.3 is a low noise, low dropout (LDO) regulator optimized for portable applications requiring a stable 3.3V output. It provides a tightly regulated 3.3V OUTPUT ONLY voltage rating. With a 100mA OUTPUT ONLY current rating, it’s well-suited for powering sensitive analog circuitry. Offered in a space-saving 5-lead SOT-23 SMD package type, the LT1761ES5-3.3 exhibits excellent thermal performance within the –40°C to 125°C operating temperature range. Common use cases include post-regulation for switching power supplies, powering RF transceivers, and noise-sensitive instrumentation. Its advantages in circuit design include its low quiescent current (typically 20µA), reverse battery protection, and short-circuit/over-temperature protection, ensuring robust and reliable operation in demanding environments. The fixed 3.3V output eliminates the need for external feedback resistors, simplifying design and minimizing component count.
