HM72XX
5mA~450mA Constant Current Regulator
MAIN APPLICATIONS
INTRODUCTION
•
•
•
•
LED Light Bars
LED Bulbs
The HM72XX-series products are linear constant current
regulators. With simple features, the HM72XX are economical
devices designed to provide a cost-effective solution for
current regulation of LED applications. The HM72XXlets LEDs
work under stable current and avoid brightness unstable
caused by current change, while their low voltage reduces
power consumption.
LED Fluorescent Lights
LED Backlight
FEATURE HIGHLIGHTS
•
•
•
•
•
Wide output voltage range: 2V~40V
Negative temperature coefficient
Accurate sink current: ±3%
With function of negative temperature coefficient, HM72XX
can protect LEDs from thermal runaway at extreme current.
HM72XX also provides a wide constant current range from
5mA to 450mA.
–40 oC ~+85 oC operation temperature range
Packages of SOT23-3, SOT89-3, SOT223, and TO252 are
available.
Pb-free and green packages:
SOT23-3, SOT89-3, SOT223, TO252
Output current: 5mA~450mA

General Notes
APPLICATION INFORMATION
For improved readability, the specification contains many application data points. When application information is given, it is advisory and does not
form part of the specification for the device.
BARE DIE DISCLAIMER
All die are tested and are guaranteed to comply with all data sheet limits up to the point of wafer sawing. There is no post waffle saw/pack testing
performed on individual die. Although the latest modern processes are utilized for wafer sawing and die pick-&-place into waffle pack carriers,
H&M SEMI has no control of third party procedures in the handling, packing or assembly of the die. Accordingly, it is the responsibility of the
customer to test and qualify their application in which the die is to be used. H&M SEMI assumes no liability for device functionality or performance of
the die or systems after handling, packing or assembly of the die.
LIFE SUPPORT APPLICATIONS
These devices are not designed for use in life support appliances, or systems where malfunction of these products can reasonably be expected to
result in personal injuries. Customer using or selling these products for use in such applications do so at their own risk.
CONTENT DISCLAIMER
H&M SEMI believes the information contained in this document to be accurate and reliable. However, it is subject to change without notice. No

Note:
(1) The condition can be achieved with the test circuit only. The Current Accuracy may be affected by negative temperature
coefficient and inappropriate package.
(2) For HM7230/HM7235/HM7240/HM7245 high current applications, it is necessary to add a heat sink to lower the case
temperature to below 50oC to guarantee the current accuracy of ±3%.
