The HP6215S3-50 is a low-dropout (LDO) regulator produced by Hypower Microelectronics. This device has been designed to provide a low-noise, stable voltage source over a wide temperature and load range. The HP6215S3-50 features an 18V-Input voltage, 40mA static output current, and 50mV typical dropout voltage. This device also has a wide input voltage range of 4V to 24V and can operate with an output voltage range of 1.35V to 18V. This regulator is packaged in a SOT23-3 RoHS compliant package, making it a space-saving solution to a wide range of applications. It is designed to provide excellent power supply ripple rejection and high thermal stability, with no need for heat sinking. The HP6215S3-50 is suitable for powering DSP/MCUs, modems, LCD displays, and other advanced, low-noise and low-power electronic circuits.
