Independent 300mA Low-Dropout Regulator
Power-good Monitor on the LDO Output with 300mS Delay
Both Outputs Internally Compensated
Independent Shutdown for the Buck and LDO Outputs
Automatic PWM to PFM mode transition
Small 10-Pin 3x3 DFN and MSOP
Undervoltage Lockout (UVLO)
Output Short Circuit and Overtemperature Protection

应用 Application

• Cellular Phones
• Portable Computers
• USB-Powered Devices
• Handheld Medical Instruments
• Organizers and PDAs
