NCP715
50 mA Ultra-Low Iq, Wide
Input Voltage, Low Dropout
Linear Voltage Regulator
The NCP715 is 50 mA LDO Linear Voltage Regulator. It is a very
stable and accurate device with ultra−low ground current consumption
(4.7
mA
over the full output load range) and a wide input voltage range
(up to 24 V). The regulator incorporates several protection features
such as Thermal Shutdown and Current Limiting.
