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