LP3981IMM-2.5/NOPB

TEXAS INSTRUMENTS  LP3981IMM-2.5/NOPB  固定电压稳压器, LDO, 2.5V至6V, 132mV压差, 2.5V输出, 300mA输出, VSSOP-8

The is a 2.5V fixed output ultra-low-dropout LDO CMOS Linear Regulator optimized for battery-powered systems to deliver ultra-low-noise and low quiescent current. Regulator ground current increases only slightly in dropout, further prolonging the battery life. Power supply rejection is better than 60dB at low frequencies. This high power supply rejection is maintained down to lower input voltage levels common to battery-operated circuits.
