LP2987

具有可编程上电复位延迟的微功耗，200 mA 超低压降电压稳压器

The /8 are fixed-output 200 mA precision LDO voltage regulators with power-ON reset delay which can be implemented using a single external capacitor.

The LP2988 is specifically designed for noise-critical applications. A single external capacitor connected to the Bypass pin reduces regulator output noise.

Using an optimized VIP Vertically Integrated PNP process, these regulators deliver superior performance:

**Dropout Voltage:** 180 mV @ 200 mA load, and 1 mV @ 1 mA load typical.

**Ground Pin Current:** 1 mA @ 200 mA load, and 200 μA @ 10 mA load typical.

**Sleep Mode:** The LP2987/8 draws less than 2 μA quiescent current when shutdown pin is held low.

**Error Flag/Reset:** The error flag goes low when the output drops approximately 5% below nominal. This pin also provides a power-ON reset signal if a capacitor is connected to the DELAY pin.

**Precision Output:** Standard product versions of the LP2987 and LP2988 are available with output voltages of 5.0V, 3.8V, 3.3V, 3.2V, 3.0V, or 2.8V, with specified accuracy of 0.5% “A” grade and 1% standard grade at room temperature.
