NCV8660B
Very Low I
q
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%.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. The output voltage must not exceed the input voltage.
2. External resistor required to minimize current to less than 1 mA when the control voltage is above 16 V.
3. This device series incorporates ESD protection and is tested by the following methods:
ESD HBM tested per AEC−Q100−002 (EIA/JESD22−A114)
ESD MM tested per AEC−Q100−003 (EIA/JESD22−A115)
ESD CDM tested per EIA/JESD22/C101, Field Induced Charge Model
4. Values represented typical steady−state thermal performance on 1 oz. copper FR4 PCB with 1 in
