LP2987ILD-3.3/NOPB
具有电源正常指示和使能功能的 200mA、16V、低压降稳压器 8-WSON -40 to 125
The LP2987/8 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.
