The LP2980 is a 50 mA, fixed-output voltage regulator designed specifically to meet the requirements of battery-powered applications. It delivers unmatched performance in all specifications critical to battery-powered designs using an optimized VIP™ process.
The LP2980 micropower regulator is designed for battery‑powered applications. It provides a typical dropout voltage of 120 mV at 50 mA load, ground‑pin current of 375 µA at the same load, and less than 1 µA quiescent current in sleep mode. The device requires only 1 µF of external capacitance and is available in 5.0 V, 3.3 V, and 3.0 V fixed‑output versions.
Typical applications include cellular phones, PDAs, camcorders, and other portable electronics. Ordering information, package dimensions, and absolute maximum ratings are detailed in the document, along with typical performance curves and application hints for optimal use.
| Dropout Voltage (typical @ 50 mA) | 120 mV |
|---|---|
| Ground Pin Current (typical @ 50 mA) | 375 µA |
| Sleep Mode Quiescent Current | < 1 µA |
| Output Voltage Accuracy | 0.5 % (A‑grade) |
| Maximum Output Current (guaranteed) | 50 mA |
| Peak Output Current (typical) | 150 mA |
| Input Supply Voltage (operating range) | 2.1 V to 16 V |

The typical dropout voltage is 120 mV when the device is delivering 50 mA.
In sleep mode, the regulator draws less than 1 µA when the ON/OFF pin is pulled low.
Only 1 µF of external capacitance on the regulator output is required for stability.
The LP2980 is offered in a 5‑lead Small Outline Package (M5) and a micro‑SMD 5‑bump package (BPA05).
