The VRH2501NLX with Dropout Regulators (LDO) LLP-4 RoHS is a Low Dropout (LDO) voltage regulator manufactured by AnaSem. It is a four-terminal (four-lead) linear voltage regulator with an operating voltage range of 1.2V to 5.5V, and a maximum output current of 500mA. Its dropout voltage is typically 0.3V at full load, and it is capable of supplying currents with low ripple and noise. It features low power dissipation and high temperature stability with a temperature range of -40 to 125°C. It can be used in a wide range of applications, including small, low-power devices, battery-powered devices, and application-specific integrated circuit (ASIC) and field-programmable gate array (FPGA) designs. It is also compliant with Restriction of Hazardous Substances (RoHS) standards.
