The MIC5246 is a low-noise LDO produced by Micrel, which has ultra-low dropout and high precision. It is suitable for applications with high requirements for power stability.
The MIC5246 is a 150 mA CMOS low‑dropout voltage regulator designed for low‑noise, battery‑powered applications. It offers ultralow dropout (100 mV @ 100 mA), a low ground current, and an error‑flag output for fault detection.
The document includes pin configuration, electrical characteristics, typical performance curves, thermal considerations, and recommended application circuits, including guidance on input and output capacitors and enable‑pin operation.
| Maximum Output Current | 150 mA |
|---|---|
| Dropout Voltage | 100 mV @ 100 mA (typical) |
| Thermal Shutdown Temperature | 150 °C |
The typical dropout voltage is 100 mV at 100 mA and rises to about 150 mV at the full 150 mA load.
