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.
Output Voltage
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
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.
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.

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.
Reset Delay Time Select
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
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.
DT=GND Reset Time NCV86601B NCV86602B NCV86603B NCV86604B 8 ms 8 ms 16 ms 32 ms DT=OUT Reset Time 128 ms 32 ms 64 ms 128 ms
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.
