LP2987 - 200 mA Ultra Low-Dropout Voltage Regulator

Description

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.

LP2987/LP2988 Micropower, 200 mA Ultra Low-Dropout Voltage Regulator with Programmable Power-On Reset Delay March 1999 LP2987/LP2988 Micropower, 200 mA Ultra Low-Dropout Voltage Regulator with Programmable Power-On Reset Delay; Low Noise Version Available (LP2988) General Description 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).
