LM1501BGR-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM1501BGR-5.0 is a monolithic integrated circuit step-down switching regulator manufactured by TAEJIN Technology. It provides a fixed 5.0V output voltage and is capable of driving a guaranteed 5.0A load current with excellent line and load regulation. The device operates at a fixed internal oscillator frequency of 300kHz, allowing for the use of small external components. It accepts an input voltage range up to 40V. Key electrical specifications include a maximum output voltage tolerance of ±3% over line and load conditions and an oscillator frequency tolerance of ±15%. The regulator features a low power standby mode with a typical quiescent current of 80uA.
