Features

General Description

❏

Accepts inputs from 15V to 450V

The Supertex LR6 is a high input voltage, low output current

linear regulator. It has a 3-terminal fixed output voltage version

available in TO-92, TO-220 and SOT-89 packages as well as an

adjustable voltage version available in 8 pin SOIC package.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.

Compatible with industry standard PWM ICs.

See application note AN-H28.

❏

Output currents up to 3mA continuous, 30mA peak

Supply current typically 50µA

Line regulation typically 0.1mV/V

Output can be trimmed from 8.0V to 12V

Output current can be increased to 150mA with external FET

The adjustable voltage version allows trimming of the output

voltage from 8V to 12V.This version can also be connected to an

external depletion mode MOSFET for increased output current.

WhenusedinconjunctionwithSupertexdepletionmodeMOSFET

DN2540N5, up to a 150mA is achieved.

Applications

❏

Off-line SMPS startup circuits (pulse loads)

Low power off-line regulators

Regulators for noisy inputs

(continued on page 14-3)

Pin Configuration

Caution

The LR6 does NOT provide galvanic isolation. When

operated from an AC line, potentially lethal voltages can be

present on the IC. Adequate means of protecting the end

user from such voltages must be provided by the circuit

developer.
