High-Voltage Linear Voltage and Current Regulators

This family consists of Microchip’s CL family of current regulators and LR family of voltage linear regulators. These voltage regulators can operate from input voltages up to 450V, with fixed and adjustable version sourcing from 10 mA to 50 mA. The current regulators operate up to 220V, with currents up to 100 mA. They support a variety of applications, including biasing and LED lighting.

The voltage regulators can operate from input voltages up to 450V, fixed and adjustable version sourcing from 10 mA to 50 mA.  They support a variety of requirements and applications.  Some  are designed to provide auxiliary start-up capability for offline switchers, for example, when a repetitive power supply starts or excessive starting power threatens long-term reliability due to excessive heat in traditional IC start-up circuits. They are also used when higher start-up regulator power is required, or if this power is required during modes where the switching regulator power is not available.
