October 25, 2016 1.5A, Radiation Hardened, Positive, High Voltage LDO
The ISL75052SEH is a radiation hardened, single output LDO
specified for an output current of 1.5A. The device operates
from an input voltage range of 4.0V to 13.2V and provides for
output voltages of 0.6V to 12.7V. The output is adjustable
based on a resistor divider setting. Dropout voltages as low as
75mV (at 0.5A) typical can be realized using the device. This
allows the user to improve the system efficiency by lowering
VIN to nearly VOUT. Features The ENABLE feature allows the part to be placed into a low
shutdown current mode of 165ВµA (typical). When enabled, the
device operates with a low ground current of 11mA (typical),
which provides for operation with low quiescent power
consumption. Ultra low dropout:
-75mV dropout (typical) at 0.5A
-225mV dropout (typical) at 1.5A The device has superior transient response and is designed
keeping single event effects in mind. This results in reduction
of the magnitude of SET seen on the output. There is no need
for additional protection diodes and filters. SET mitigation with no added filtering/diodes A COMP pin is provided to enable the use of external
compensation. This is achieved by connecting a resistor and
capacitor from COMP to ground. The device is stable with …
