TEXAS INSTRUMENTS LP5907 Fixed LDO Voltage Regulator, 2.2-5.5V In, 250mA, SOT-5 - 3.3V

The TEXAS INSTRUMENTS LP5907 is a high-performance, fixed-output Low Dropout (LDO) linear voltage regulator designed specifically for noise-sensitive applications, such as RF and analogue circuits. This ultra-low-noise regulator delivers exceptional Power Supply Rejection Ratio (PSRR), minimal quiescent current, and fast line or load transient response, ensuring a clean and stable power supply for your most demanding designs.

Utilising innovative design techniques, the LP5907 achieves best-in-class noise performance without the need for a dedicated noise bypass capacitor. It also offers the unique advantage of remote output capacitor placement, simplifying PCB layout and increasing design flexibility. The device is optimised to operate with just a 1µF ceramic input capacitor and a single 1µF ceramic output capacitor, which can be placed up to 10cm away from the regulator itself.

Engineered for reliability, the LP5907 incorporates comprehensive protection features, including thermal overload and short circuit protection. Its exceptionally low dropout voltage maximises efficiency and extends battery life in portable applications. The regulator also features near-zero shutdown current, making it ideal for power-conscious designs where energy efficiency is paramount.

With its robust performance across a wide temperature range, this component is a trusted solution for creating stable and efficient power rails in complex electronic systems, where precision and reliability are non-negotiable.
