The Microchip LDO Regulator is a high input voltage, low output current linear regulator. The 3-terminal version functions like any other low voltage 3-terminal regulator except it allows the use of much higher input voltages. When used in a SMPS start-up circuit, it eliminates the need for large power resistors. In this application, current is drawn from the high voltage line only during start-up. Only leakage current flows after start-up, thereby reducing the continuous power dissipation to a few milliwatts.
Accepts inputs from 15 to 450V
Output currents up to 3.0mA continuous and 30mA peak
Supply current typically 50μA
Output can be trimmed from 8.0 to 12V
Output current can be increased to 150mA with external FET
