What are the key features of LDL212PU12R?
- Ultra-low dropout voltage of 1.3V (typ) enables efficient regulation from low input supplies down to 2.5V
- High power supply rejection ratio (PSRR) exceeding 60dB at 1kHz for clean output even with noisy inputs
- Fixed 1.2V output with tight ±2% accuracy in a tiny 6-pin SOT-23 package for space-constrained designs
What is LDL212PU12R used for?
The LDL212PU12R is well suited for powering microcontrollers, sensors, and RF modules in battery-operated IoT and wearable devices where the 1.2V output and low quiescent current extend battery life. Its high PSRR makes it ideal as a post-regulator behind switching converters in noise-sensitive analog and RF applications. It also serves well in portable consumer electronics and industrial sensor nodes requiring a stable low-voltage rail from a 3.3V or 5V system bus.

Frequently Asked Questions
What is the maximum output current the LDL212PU12R can deliver continuously?
The LDL212PU12R is rated for a maximum continuous output current of 300mA, making it suitable for powering low-power microcontrollers, sensors, and RF front-ends in compact portable designs.
How much dropout voltage does the LDL212PU12R exhibit at full load, and why does it matter for battery-powered designs?
At full 300mA load, the LDL212PU12R has a typical dropout voltage of 1.3V, meaning the input supply can drop to within 1.3V of the 1.2V output before regulation is lost—critical for extending usable battery life in portable devices operating from a single Li-ion cell.
Which noise-sensitive applications benefit most from the LDL212PU12R's PSRR performance?
Applications such as RF transceivers, audio ADCs, and precision analog sensor circuits benefit most. The LDL212PU12R provides more than 60dB PSRR at 1kHz, effectively attenuating switching noise from upstream DC-DC converters and keeping the 1.2V supply rail clean for sensitive circuitry.
What input voltage range does the LDL212PU12R support, and what are its absolute maximum limits?
The LDL212PU12R operates from a 2.5V to 18V input voltage range in normal operation, with an absolute maximum input rating of 20V. This wide range accommodates diverse supply sources from single-cell Li-ion batteries up to 12V industrial rails.
