LP3981ILD-3.0/NOPB

具有使能功能的 300mA、高精度、低压降稳压器 6-WSON

Performance of the LP3981 device is optimized for battery-powered systems to deliver ultra-low-noise, extremely low dropout voltage, and low quiescent current. Regulator ground current increases only slightly in dropout, further prolonging the battery life.

Power supply rejection is better than 60 dB at low frequencies. This high power supply rejection is maintained down to lower input voltage levels common to battery-operated circuits.

The device is ideal for mobile phone and similar battery-powered wireless applications. It provides up to 300 mA, from a 2.5-V to 6-V input, consuming less than 1 µA in disable mode.

The LP3981 is available in 8-pin VSSOP-8 and 6-pin WSON packages. Performance is specified for −40°C to +125°C temperature range. The device available in the following output voltages: 2.5 V, 2.7 V, 2.8 V, 2.83 V, 3 V, 3.03 V and 3.3 V as standard. Other output options can be made available; contact your local sales office for more information.
