OTECHThe HE6350MPR Linear Voltage Regulators (LDO) ROHS manufactured by HEERMICROTECH are a SOT-89-3 package with a 5.0V constant voltage output, a 250mA maximum current output, a 500mV dropout voltage, a 2µA low quiescent current, and a 40dB@1kHz power supply ripple rejection rate. It also has an input voltage ranging from 5.0V to 18V. These regulators are designed to provide a very low noise, low voltage power supply solution. They are suitable for regulating both linear and switching supplies, and have additional features such as adjustable current limit, over voltage protection, and overtemperature protection.
