The ZLDO330 low dropout linear regulator provides an output voltage of 3.3V with a typical quiescent current of only 560µA and a dropout voltage of 30mV at 100mA. It is packaged in the Zetex SM8 small outline surface mount package, ideal for space-saving applications.
The ZLDO330 regulator provides a fixed 3.3 V output with an exceptionally low dropout voltage—typically 6 mV at 10 mA, 30 mV at 100 mA, and 100 mV at 300 mA. It consumes only 560 µA quiescent current in normal operation and can drop to about 11 pA when shutdown is enabled, making it ideal for battery‑powered designs.
Packaged in an SM8 surface‑mount package, the device operates from –0.3 V to 20 V input, supports up to 300 mA load current, and includes a low‑battery flag and over‑temperature shutdown. Typical applications include portable instruments, communications equipment, and low‑power laptops.
| Output voltage (typical) | 3.3 V |
|---|---|
| Dropout voltage at 10 mA | 6 mV |
| Dropout voltage at 100 mA | 30 mV |
| Dropout voltage at 300 mA | 100 mV |
| Quiescent current (shutdown) | 11 pA typ |
| Operating temperature range | -40 °C to 85 °C |
The dropout voltage is 30 mV at a 100 mA load.
When shutdown is active, the quiescent current drops to about 11 pA.
