FEATURES
● Wide working voltage range : 15V to 450V● Output current up to 3.0mA continuous supply, 30mA peak value
● Supply current : 250µA (typically)
● Line regulation : 0.1mV/V (typically)
● Output Voltage: 5V, 9V, 12V
APPLICATIONS
● Off-line SMPS PWM controller startup circuitGENERAL DESCRIPTION
Other than the functions like ordinary low voltage regulators, the LD7301 provides the use of much higher input voltages (up to 450V). In this application, current is drawn from the high voltage line only during start-up. There is only current flow leakage after start-up, thereby reducing the continuous power dissipation from milliwatts to watts.
