General Description
The MIC5237 is a general-purpose low-dropout regulator capable of 500mA output current with better than 3% output voltage accuracy. Using Micrel’s proprietary Super ßeta PNP® process with a PNP pass element, these regulators feature less than 300mV dropout voltage and typically 8mA ground current at full load.

Features
• Guaranteed 500mA output over the full operating temperature range
• Low 300mV typical dropout voltage at full load
• Extremely tight load and line regulation
• Current and thermal limiting
• Reversed-battery protection
• TO-220 and TO-263 packages
• Low temperature coefficient
• No-load stability
• Low-noise output

Applications
• Portable and laptop computers
• Desktop computer
• Battery chargers
• SMPS post-regulator/dc-to-dc modules
• Consumer and personal electronics
