illustrate
The LP5990 regulator is designed to meet the requirements of portable, battery-powered systems to provide precise output voltage, low noise and low quiescent current.
The LP5990 will provide a low input voltage of 2.2V from a 1.8V output and can provide 200mA to an external load.
When switching into shutdown mode, power consumption is reduced to almost by enabling the logic signal on the pin
is zero.
The rapid shutdown is achieved by a push-pull architecture.
LP5990是设计与节省空间的0402为1μF小型的陶瓷电容器稳定，这给出了一个 整体解决方案 大小
Specifies a junction temperature range of -40°C to 125°C.
The device is available in a micro SMD package (0.4mm pitch) and can be used with 1.2V, 1.3V, 1.8V, 2.8V, 3.0V, 3.3V, and 3.6V outputs. The voltage drops to 0.8V and is available on request. For all other output voltage options, contact your local NSC sales office.
