The CM3016-48 is a low power, 4.75V/500mA low noise CMOS LDO regulator produced by California Micro Devices Corp.
The CM3016-48 linear regulator provides a stable 4.75 V output with up to 500 mA load current, making it suitable for notebook computers, consumer electronics and audio codecs. It features a dedicated enable pin, optional noise‑bypass capacitor, and is available with a lead‑free finish.
Key features include low dropout voltage (150 mV at 150 mA), ultra‑low noise, fast power‑up, foldback current limiting, reverse‑current protection, and thermal overload shutdown. The device is stable with or without an output capacitor and is housed in a compact 5‑pin SOT‑23 package.
| Output Voltage (typical) | 4.75 V |
|---|---|
| Maximum Output Current | 500 mA |
| Dropout Voltage (150 mA load) | 150 mV |
| Quiescent Current (light load) | 150 µA |
| Input Voltage Range | 4.6 V to 6.0 V |
| Operating Temperature Range | -40 °C to +85 °C |
| Package | 5‑pin SOT‑23 |
The regulator can supply up to 500 mA of output current.
Pull the EN pin low (below 0.4 V) to disable the regulator; the supply current then drops to near zero.
It includes overload current limiting, foldback current limiting, thermal shutdown, and reverse‑current protection.
No, the device is stable without an output capacitor, though any type can be added to improve transient response.
