Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
STMicroelectronics L4947 is a fixed 5V positive linear voltage regulator, delivering up to 500mA output current. This Pentawatt-5 package device features a low quiescent current of 13mA and an input voltage capability up to 26V. Protection includes over-temperature, reverse polarity, and short-circuit safeguards. The L4947 offers a typical voltage dropout of 0.75V at 500mA and a Power Supply Rejection Ratio (PSRR) of 60dB at 120Hz. Control features include a reset function. This component is commonly utilized in automotive, industrial, and consumer electronics applications requiring stable voltage regulation.
