LP2988

The LP2987/8 are fixed-output 200mA precision LDO volt- age regulators with power-ON reset delay which canbe implemented using a single external capacitor.

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

Using an optimized VIP™ (Vertically Integrated PNP) pro-cess,these regulators deliver superior performance:
Dropout Voltage:180mV @ 200mA load,and 1mV @ 1mA load (typical).
Ground Pin Current: 1mA @ 200mA load,and 200µA @ 10mA load (typical).
Sleep Mode: The LP2987/8 draws less than 2µA 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 pro-vides a power ON reset signal if acapacitor 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,or2.8V,with guaranteed accuracy of 0.5%("A"grade) and 1% (standard grade) at room temperature.
