LP2988A Micropower 3.0V 200 mA Ultra LDO Regulator with Programmable Power-On Reset Delay

Manufactured by National Semiconductor - Part # LP2988AIMMX-3.0 -  SOIC8 SMD Package

DESCRIPTION

The LP2988 is a fixed-output 200 mA precision LDO voltage regulator 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 mAload, 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 LP2988 draws less than 2 μA quiescent current when shutdown pin is held low

FEATURES

• Ultra low dropout voltage
• Power-ON reset delay requires only one component
• Bypass pin for reduced output noise (LP2988)
• Guaranteed continuous output current 200 mA
• Guaranteed peak output current > 250 mA
• SO-8 and mini SO-8 surface mount packages
• <2 μA quiescent current when shutdown
• Low ground pin current at all loads
• 0.5% output voltage accuracy (A grade)
• Wide supply voltage range (16V max)
• Overtemperature/overcurrent protection
• −40°C to +125°C junction temperature range
