Note:
(1)
Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the
device. These are stress ratings only, and functional operation of the device at these or any other
conditions beyond those indicated under recommended operating conditions is not implied.
Exposure to absolute-maximum-rated conditions for extended periods my affect device reliability.
(2)
All voltages are with respect to network ground terminal.
(3)
The ACE5019A includes over temperature protection that is intended to protect the device during
momentary overload. Junction temperature will exceed 125°C when over temperature protection is
active. Continuous operation above the specified maximum operating junction temperature may
impair device reliability.
(4)
ESD testing is performed according to the respective JESD22 JEDEC standard.
The human body model is a 100 pF capacitor discharged through a 1.5kΩ resistor into each pin. The
machine model is a 200pF capacitor discharged directly into each pin.

Application Information
Selection of Input/ Output Capacitors
In general, all the capacitors need to be low leakage. Any leakage the capacitors have will reduce
efficiency, increase the quiescent current.
A recent trend in the design of portable devices has been to use ceramic capacitors to filter DC-DC
converter inputs. Ceramic capacitors are often chosen because of their small size, low equivalent series
resistance (ESR) and high RMS current capability. Also, recently, designers have been looking to ceramic
capacitors due to shortages of tantalum capacitors.
Unfortunately, using ceramic capacitors for input filtering can cause problems. Applying a voltage step to
a ceramic capacitor causes a large current surge that stores energy in the inductances of the power leads.
A large voltage spike is created when the stored energy is transferred from these inductances into the
ceramic capacitor. These voltage spikes can easily be twice the amplitude of the input voltage step. (See
“Ceramic Input Capacitors Can Cause Overvoltage Transients”——Linear Technology application note 88,
March 2001)
Many types of capacitors can be used for input bypassing; however, caution must be exercised when
using multilayer ceramic capacitors (MLCC). Because of the self-resonant and high Q characteristics of
some types of ceramic capacitors, high voltage transients can be generated under some start-up
conditions, such as connecting the LDO input to a live power source. Adding a 3Ω resistor in series with
an X5R ceramic capacitor will
minimize start-up voltage transients.
The LDO also requires an output capacitor for loop stability. Connect a 1μF tantalum capacitor from OUT
to GND close to the pins. For improved transient response, this output capacitor may be ceramic.
