The LP3878-ADJ is a 800mA adjustable output voltage regulator designed by TI. It features low quiescent current, low noise and low temperature drift. It is suitable for applications that require output voltage as low as 1.0V.
The LP3878-ADJ is an 800 mA adjustable output voltage regulator designed for high performance and low noise in applications requiring output voltages as low as 1 V. It features a VIP™ (Vertically Integrated PNP) process, low ground‑pin current, and a shutdown pin that reduces quiescent current to under 10 µA.
The device is offered in 8‑Lead PSOP (MRA) and 8‑Lead LLP (SD) surface‑mount packages, supports a wide operating temperature range of –40 °C to +125 °C, and includes over‑temperature and over‑current protection. Detailed electrical characteristics, absolute maximum ratings, and typical performance graphs are provided for design reference.
| Output current | 800 mA |
|---|---|
| Output voltage range | 1.0 V to 5.5 V |
| Ground pin current (typical) | 5.5 mA @ 800 mA load |
| Operating temperature range | -40 °C to +125 °C |
The ground pin current is typically 5.5 mA when the device is delivering 800 mA load.
