LP3990MF-1.8

TEXAS INSTRUMENTS  LP3990MF-1.8  固定电压稳压器, LDO, 2V至6V, 120mV压差, 1.8V输出, 150mA输出, SOT-23-5

The is a 1.8V fixed output Linear Regulator designed to meet the requirements of portable, battery-powered systems providing an accurate output voltage, low-noise and low-quiescent current. The device will provide a 0.8V output from the low input voltage of 2V at up to a 150mA load current. When switched into shutdown mode via a logic signal at the enable pin EN, the power consumption is reduced to virtually zero. The device is designed to be stable with space-saving ceramic capacitors with values as low as 1µF.
