DescriptionThe 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 guaranteed accuracy of 0.5% ("A" grade) and 1% (standard grade) at room temperature.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.For more information on Reliability Metrics, please click here.
