Very Low Iq Low Dropout Linear Regulator

ON Semiconductor 

NCV8664C

Very Low Iq Low Dropout

Linear Regulator

The NCV8664C is a precision 3.3 V and 5.0 V fixed output, low

dropout integrated voltage regulator with an output current

capability of 150 mA. Careful management of light load current

consumption, combined with a low leakage process, achieve a

typical quiescent current of 22 mA.

NCV8664C is pin and functionally compatible with NCV4264−2C

and could replace this part when lower quiescent current is required.

The output voltage is accurate within ±2.0 %, and maximum

dropout voltage is 600 mV at full rated load current.

It is internally protected against input supply reversal, output

overcurrent faults, and excess die temperature. No external

components are required to enable these features.

Features

• 3.3 V, 5.0 V Fixed Output

• Internal Fault Protection

♦ −42 V Reverse Voltage

♦ Short Circuit/Overcurrent

♦ Thermal Overload

• EMC Compliant

• AEC−Q100 Grade 1 Qualified and PPAP Capable

• These are Pb−Free Devices
