NCV8660B
Very Low Iq LD0 150 mA
Regulator with RESET and
Delay Time Select
The NCV8660B is a precision very low Iq low dropout voltage
regulator. Quiescent currents as low as 28 mA typical make it ideal for
automotive applications requiring low quiescent current with or
without a load. Integrated control features such as Reset and Delay
Time Select make it ideal for powering microprocessors.
It is available with a fixed output voltage of 5.0 V and 3.3 V and
regulates within ±2.0%.

NCV8660B
DETAILED OPERATING DESCRIPTION
General
Current Limit
The NCV8660B is a 5 V and 3.3 V linear regulator
providing low drop−out voltage for 150 mA at low quiescent
current levels. Also featured in this part is a reset output with
selectable delay times. Delay times are selectable via part
selection and control through the Delay Time Select (DT)
pin. No pull−up resistor is needed on the reset output (RO).
Pull−up and pull−down capability are included. Only a small
bypass capacitor on the input (IN) supply pin and output
(OUT) voltage pin are required for normal operation.
Thermal shutdown functionality protects the IC from
damage caused from excessively high temperatures
appearing on the IC.
Current limit is provided on OUT to protect the IC. The
minimum specification is 205 mA. Current limit is specified
under two conditions (OUT = 96% x OUT nominal) and
(OUT = 0 V). No fold−back circuitry exists. Any measured
differences can be attributed to change in die temperature.
The part may be operated up to 205 mA provided thermal die
temperature is considered and is kept below 150°C.
Degradation of electrical parameters at this current is
expected at these elevated levels. A reset (RO) will not occur
with a load less than 205 mA.
Reset Output
A reset signal is provided on the Reset Output (RO) pin to
provide feedback to the microprocessor of an out of
regulation condition. This is in the form of a logic signal on
RO. Output (OUT) voltage conditions below the RESET
threshold cause RO to go low. The RO integrity is
maintained down to OUT = 1.0 V.
The Reset Output (RO) circuitry includes an active
internal pullup to the output (OUT) as shown in Figure 24.
No external pullup is neccessary.
Output Voltage
Output stability is determined by the capacitor selected
from OUT to GND. The NCV8660B has been designed to
work with low ESR (equivalent series resistance) ceramic
capacitors. The device is extremely stable using virtually
any capacitor 2.2 mF and above. Reference the Output
Capacitor Stability graph in Figure 21.
The output capacitor value will affect overshoot during
power−up. A lower value capacitor will cause higher
overshoot on the output. System evaluation should be
performed with minimum loading for evaluation of
overshoot.
Selection of process technology for the NCV8660B
allows for low quiescent current independent of loading.
Quiescent current will remain flat across the entire range of
loads providing a low quiescent current condition in standby
and under heavy loads. This is highly beneficial to systems
requiring microprocessor interrupts during standby mode as
duty cycle and load changes have no impact on the standby
current. Reference Figure 14 for Quiescent Current vs
Output Current.

Figure 25. Reset Timing
During power−up (or restoring OUT voltage from a reset
event), the OUT voltage must be maintained above the Reset
threshold for the Reset Delay time before RO goes high. The
time for Reset Delay is determined by the choice of IC and
the state of the DT pin.
The Delay Time select (DT) pin is logic level controlled
and provides Reset Delay time per the chart. Note the DT pin
is sampled only when RO is low, and changes to the DT pin
when RO is high will not effect the reset delay time.
Thermal Shutdown
When the die temperature exceeds the Thermal Shutdown
threshold, a Thermal Shutdown event is detected OUT is
turned off, and RO goes low. The IC will remain in this state
until the die temperature moves below the shutdown
threshold (175°C typical) minus the hysteresis factor (25°C
typical). The output will then turn back on and RO will go
high after the RESET Delay time.
Reset Delay Time Select
Selection of the NCV8660B device and the state of the DT
pin determines the available Reset Delay times. The part is
designed for use with DT tied to ground or OUT, but may be
controlled by any logic signal which provides a threshold
between 0.8 V and 2 V. The default condition for an open DT
pin is the slower Reset time (DT = GND condition). Times
are in pairs and are highlighted in the chart below. Consult
factory for availability.
