5V Voltage regulator

Precision 5 V Linear Regulator – Low Dropout, High Efficiency

This 5 V fixed-output regulator delivers clean, low‑noise power for microcontrollers, digital logic, and sensitive ADCs. Built on an LDO architecture, it provides a stable voltage with minimal dropout, making it ideal for battery‑powered devices with tight voltage margins. The integrated 120 mOhm dropout capacitor and pass‑transistor current mirror ensure fast dynamic response and excellent line‑ and load‑rejection.

With a typical quiescent current of <50 µA and a load‑rejection ratio of 65 dB, the regulator guarantees precise power delivery even in high‑frequency digital systems. Thermal shutdown and under‑current protection automatically recover the circuit from transient faults, extending component longevity in extreme environments.
