Micropower 400 mA  
LDO Linear Regulators  
with ENABLE, DELAY,  
and RESET  
http://onsemi.com  
The NCV8505 is a family of precision micropower voltage  
regulators. Their output current capability is 400 mA. The family has  
output voltage options for Adjustable, 2.5 V, 3.3 V and 5.0 V.  
The output voltage is accurate within ± 2.0% with a maximum  
dropout voltage of 0.6 V at 400 mA. Low quiescent current is a feature  
drawing less than 1.0 µA with ENABLE = 0 V. With ENABLE = 5.0 V,  
the part only draws 200 µA with 100 µA load. This part is ideal for any  
and all battery operated microprocessor equipment.  
MARKING

NCV8505x  
AWLYYWW  
Microprocessor control logic includes an active RESET (with  
DELAY).  
The active RESET circuit operates correctly at an output voltage as  
low as 1.0 V. The RESET function is activated during the power up  
sequence or during normal operation if the output voltage drops below  
the regulation limits.  
The regulator is protected against reverse battery, short circuit, and  
thermal overload conditions. The device can withstand load dump  
transients making it suitable for use in automotive environments. The  
device has also been optimized for EMC conditions.

CIRCUIT DESCRIPTION  
DELAY Function  
REGULATOR CONTROL FUNCTIONS  
The NCV8505 contains the microprocessor compatible  
control function RESET (Figure 13).  
The reset delay circuit provides a programmable (by  
external capacitor) delay on the RESET output lead.  
The DELAY lead provides source current (typically 4.0 µA)  
to the external DELAY capacitor during the following  
proceedings:  
V
IN  
1. During Power Up (once the regulation threshold  
has been verified).  
RESET  
V
OUT  
2. After a reset event has occurred and the device is  
back in regulation. The DELAY capacitor is  
discharged when the regulation (RESET threshold)  
has been violated. This is a latched incident. The  
capacitor will fully discharge and wait for the  
device to regulate before going through the delay  
time event again.

included in the function to minimize oscillations.

The value of R  
can then be compared with those in the

package section of the data sheet. Those packages with  
’s less than the calculated value in equation 2 will keep  
the die temperature below 150°C.  
In some cases, none of the packages will be sufficient to  
dissipate the heat generated by the IC, and an external  
heatsink will be required.  
STABILITY CONSIDERATIONS  
R
qJA  
The output or compensation capacitor helps determine  
three main characteristics of a linear regulator: start−up  
delay, load transient response and loop stability.  
The capacitor value and type should be based on cost,  
availability, size and temperature constraints. A tantalum or  
aluminum electrolytic capacitor is best, since a film or  
ceramic capacitor with almost zero ESR can cause  
instability. The aluminum electrolytic capacitor is the least  
expensive solution, but, if the circuit operates at low  
temperatures (−25°C to −40°C), both the value and ESR of  
the capacitor will vary considerably. The capacitor  
manufacturers data sheet usually provides this information.

A heat sink effectively increases the surface area of the  
package to improve the flow of heat away from the IC and  
into the surrounding air.  
Each material in the heat flow path between the IC and the  
outside environment will have a thermal resistance. Like
