CS8281-5V/250mA, 5V/100mA Micro and ENABLE Low Dropout Regulator
The CS8281 is a high precision, dual 5V micropower linear regulator. The primary output switch (VOUT1) provides up to 250mA while the secondary (VOUT2) is capable of supplying 100mA. Both outputs have low back current with a maximum dropout voltage of 600mV. Quiescent current consumption is typically 150µA to 100µA from each output when powered. The ENABLE input provides the logic level control main output. With the main output disabled, the quiescent current consumption is typically 100µA when powered from 100µA to the auxiliary output. The CS8281 is very powerful with two outputs that provide protection against reverse battery connection, short circuit, overvoltage, and overheating. The CS8281 uses a 5-pin D2PAK.
