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).
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...
