onsemi NCP785A High PSRR Linear Regulators
onsemi NCP785A High PSRR Linear Regulators offer a very wide operating input voltage range of up to 450VDC. They have an output current of up to 10mA and are ideal for high-input voltage applications. The NCP785A family offers ±5% initial accuracy, extremely high-power supply rejection ratio and ultra-low quiescent current. They are ideal for harsh environment applications and optimized for high-voltage line and load transients. The onsemi NCP785A is offered in fixed output voltage options 3.3V, 5.0V, 12V and 15V. SOT−89 package offers good thermal performance.
