Dual-Output (Fixed/Variable) LDO Regulators - BA30E00WHFPROHM's secondary LDO regulators were designed to maximize device characteristics and provide stable operation through low power consumption, increased miniaturization, and low noise. ROHM's dual output fixed/variable secondary LDO regulators for local power supplies feature two outputs (3.3V fixed/0.8V-3.3V variable) and an output voltage accuracy of ±2% along with low saturation, reducing the number of parts required as well as the mounting area. In addition, multiple protection circuits are integrated (i.e. overcurrent, thermal shutdown), providing a high level of reliability.
