NR121E General Description

The NR120E series is buck regulator ICs integrates High-side power MOSFET. With the current mode control, ultra low ESR capacitors such as ceramic capacitors can be used. The ICs have protection functions such as Over-Current Protection (OCP), Under-Voltage Lockout (UVLO) and Thermal Shutdown (TSD).
