LP3995 Micropower 150mA CMOS Voltage Regulator with Active Shutdown is a low-power switching regulator manufactured by ON Semiconductor. It has low noise, low quiescent current and other characteristics, and is suitable for powering RF/Analog devices. The device also has internal short circuit current and over-temperature protection functions.
The LP3995 linear regulator is designed for portable battery‑powered applications, providing an accurate output voltage with low noise, low dropout (typical 60 mV at 150 mA) and an active shutdown function that reduces quiescent current to virtually zero. It is stable with 1 µF ceramic output capacitors and includes internal protection against short‑circuit and over‑temperature conditions.
The device is offered in a 5‑pin micro‑SMD package (TLA05) and a 6‑pin LLP (SOT‑23) package, supports fixed output voltages from 1.5 V to 3.3 V, and operates over a temperature range of –40 °C to +125 °C. Detailed electrical characteristics, ordering information, and mechanical dimensions are provided in the handbook.
