1.5A, Radiation Hardened, Positive, High Voltage LDO

The ISL75052SEH and ISL73052SEH are radiation hardened,  
single output LDOs specified for an output current of 1.5A. The  
devices operate from an input voltage range of 4.0V to 13.2V  
and provide for output voltages of 0.6V to 12.7V. The output is  
adjustable based on a resistor divider setting. Dropout  
Features  
• DLA SMD 5962-13220  
• Input supply range 4.0V to 13.2V  
• Output current up to 1.5A at T = +150°C  
J
voltages as low as 75mV (at 0.5A) typical can be realized using  
the devices. This allows you to improve the system efficiency  
• Best in class accuracy ±1.5%  
by lowering V to nearly V  
.
- Over line, load ,and temperature  
IN OUT  
The ENABLE feature allows the part to be placed into a low  
shutdown current mode of 165µA (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  
• Noise of 100µV  
(typical) between 300Hz to 300kHz  
RMS  
• SET mitigation with no added filtering/diodes  
• Shutdown current of 165µA (typical)  
• Externally adjustable output voltage  
• PSRR 65dB (typical) at 1kHz  
These devices have superior transient response and are  
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.  
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  
tantalum capacitors as low as 47µF (KEMET T525 series) and  
provides excellent regulation all the way from no load to full  
load. The programmable soft-start allows you to program the  
inrush current by means of the decoupling capacitor used on  
the BYP pin. The OCP pin allows the short-circuit output current  
limit threshold to be programmed by means of a resistor from  
OCP pin to GND. The OCP setting range is from 0.16A  
minimum to 3.2A maximum. The resistor sets the constant  
current threshold for the output under fault conditions. The  
thermal shutdown disables the output if the device  
• ENable and PGood feature  
• Programmable soft-start/inrush current limiting  
• Adjustable overcurrent protection  
• Over-temperature shutdown  
• Stable with 47µF minimum tantalum capacitor  
• 16 Ld flatpack package
