ACE605
Ultra Low Dropout 2A CMOS LDO
Description
The ACE605 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.
The ACE605 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 overtemperature 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. 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 1.6A without the pad.

Notes:
In order to get better dropout and larger output current, keep Ven higher +0.8V or more than Vin , which also result in better
output ripple.
1. in order to have a lower ripple output voltage, pls. add a small capacitor from enable pin to ground
2. pull up enable pin to 3.3V or 5V , the voltage , the better , is higher than vin.
3. the fixed output voltage version is also adjustable via two external resistors, adjust from 0.6V .
4. if enable voltage is same as Vin , the dropout voltage is 1V , if higher than Vin + 0.8V , the dropout voltage can be less
than 0.3V

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.
2. Devices are ESD sensitive. Handling precaution recommended.
3. The device is not guaranteed to function outside its operating conditions.
4. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV.
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.
6. Quiescent, or ground current, is the difference between input and output currents. It is defined by IQ = I IN – 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.
7. Try to layout the pads larger to get better heat-sink , result in larger current output.
