General Description
The MIC5258 is an efficient, precise CMOS voltage regulator with power good output. The MIC5258 offers better than 3% initial accuracy, and constant ground current (typically 100µA)over load .

Features
• Power Good indicator
• Load independent, ultralow ground current: 100µA
• 150mA output current
• Current limiting
• Thermal shutdown
• Tight load and line regulation
• “Zero” off-mode current
• Stability with low-ESR capacitors
• Fast transient response
• TTL-Logic-controlled enable input

Applications
• Processor power-up sequencing
• Laptop, notebook, and palmtop computers
• PCMCIA VCC and VPP regulation/switching
