LR645 regulator equivalent, high-input voltage smps start-up/linear regulator.
* Accepts inputs from 15 to 450V
* Output currents: up to 3.0mA continuous, 30mA
peak
* Supply current typically 50µA
* Line regulation typically 0.1mV/V .
* Off-line SMPS startup circuits (pulse loads)
* Low power off-line regulators
* Regulators for noisy inputs.
LR645 is a high-input voltage, low-output current, linear regulator that is available in two versions. A 3-terminal, fixed-output voltage version is available in TO-92, TO220 and SOT-89 packages, as well as an adjustable voltage version available in .
