ADP1710/ADP1711  
APPLICATION INFORMATION  
CAPACITOR SELECTION  
Output Capacitor  
Input Bypass Capacitor  
Connecting a 1 μF capacitor from IN to GND reduces the  
circuit sensitivity to printed circuit board (PCB) layout,  
especially when long input traces or high source impedance are  
encountered. If greater than 1 μF of output capacitance is  
required, the input capacitor should be increased to match it.  
The ADP1710/ADP1711 are designed for operation with small,  
space-saving ceramic capacitors, but they will function with most  
commonly used capacitors as long as care is taken about the  
effective series resistance (ESR) value. The ESR of the output  
capacitor affects stability of the LDO control loop. A minimum of  
1 μF capacitance with an ESR of 500 mΩ or less is recommended  
to ensure stability of the ADP1710/ADP1711. Transient response  
to changes in load current is also affected by output capacitance.  
Using a larger value of output capacitance improves the transient  
response of the ADP1710/ADP1711 to large changes in load  
current. Figure 21 and Figure 22 show the transient responses for  
output capacitance values of 1 μF and 22 μF, respectively.  
Input and Output Capacitor Properties  
Any good quality ceramic capacitors can be used with the  
ADP1710/ADP1711, as long as they meet the minimum  
capacitance and maximum ESR requirements. Ceramic  
capacitors are manufactured with a variety of dielectrics, each  
with different behavior over temperature and applied voltage.  
Capacitors must have a dielectric adequate to ensure the  
minimum capacitance over the necessary temperature range  
and dc bias conditions. X5R or X7R dielectrics with a voltage  
rating of 6.3 V or 10 V are recommended. Y5V and Z5U  
dielectrics are not recommended, due to their poor temperature  
and dc bias characteristics.

CURRENT LIMIT AND THERMAL OVERLOAD  
PROTECTION  
1
The ADP1710/ADP1711 are protected against damage due to  
excessive power dissipation by current and thermal overload  
protection circuits. The ADP1710/ADP1711 are designed to  
current limit when the output load reaches 270 mA (typical).  
When the output load exceeds 270 mA, the output voltage is  
reduced to maintain a constant current limit.

Thermal overload protection is included, which limits the  
junction temperature to a maximum of 150°C (typical). Under  
extreme conditions (that is, high ambient temperature and  
power dissipation) when the junction temperature starts to rise  
above 150°C, the output is turned off, reducing the output  
current to zero. When the junction temperature drops below  
135°C, the output is turned on again and output current is  
restored to its nominal value.

Consider the case where a hard short from OUT to ground  
occurs. At first the ADP1710/ADP1711 current limits, so that  
only 270 mA is conducted into the short. If self heating of the  
junction is great enough to cause its temperature to rise above  
150°C, thermal shutdown activates, turning off the output and  
reducing the output current to zero. As the junction  
temperature cools and drops below 135°C, the output turns on  
and conducts 270 mA into the short, again causing the  
junction temperature to rise above 150°C. This thermal  
oscillation between 135°C and 150°C causes a current  
oscillation between 270 mA and 0 mA, which continues as  
long as the short remains at the output.
