BM9165
Ultra Low Dropout 2A CMOS LDO
General Description
Features
The BM9165 series are high performance linear voltage
regulators that provide ultra low-dropout voltage, high output
z 300mV Dropout @ 2A (1.2V output)
z <300µA Low Ground Pin Current
current in lowest output voltage. It operates from an input
of 1.4V to 5.5V and provides output current up to 2A
z Excellent Line and Load Regulation
z 0.1µA Quiescent Current in Shutdown Mode
thus is suitable to drive digital circuits requiring low voltage z Guaranteed >2A Output Current
at high currents.
z Fixed Output Voltages: 1.05V, 1.2V, 1.8V, 2.5V
The BM9165 has superior regulation over variations in line
and load. Also it provides fast respond to step changes in
z Adjustable Output Voltage from 0.6V to 4.5V
z Over-Temperature/Over-Current Protection
load. Other features include over-current and over-
temperature protection. The adjustable version has enable
pin to reduce power consumption in shutdown mode.
The devices are available ADJ output , and via exteral R
adjust output voltage from 0.6V to Vin-0.3V, 0.6V is the
reference voltage. The BM9165 have enable function ,
that is good for poratble system for main chip on and off.
Applications
z Card reader and Battery-Powered Equipment
z Mother Board/Graphic Card
z LCD-TV , NET BOOK , USB Net card
z NET-BOOK, pin-pin with RT9025, RT9018
Pin Configurations
In order to have lower dropout and bigger current output
Ven should 0.8~1.0V higher than Vin, but can work if same.
(SOP8 with pad)
Power pad sop8 can output over 2A and 1.8A without the pad.

Note 1. Stresses listed as the above "Absolute Maximum Ratings" may cause permanent damage to the device. These
are for stress ratings. Functional operation of the device at these or any other conditions beyond those indicated
in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions
for extended periods may remain possibility to affect device reliability.
Note 2. Devices are ESD sensitive. Handling precaution recommended.
Note 3. The device is not guaranteed to function outside its operating conditions.
Note 4. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV.
Note 5. Regulation is measured at constant junction temperature by using a 20ms current pulse. Devices are tested for
load regulation in the load range from 10mA to 2A.
Note 6. Quiescent, or ground current, is the difference between input and output currents. It is defined by IQ = IIN - IOUT
under no load condition (IOUT = 0mA). The total current drawn from the supply is the sum of the load current plus
the ground pin current.
