uA78M33 Positive-Voltage Linear Regulator

The UA78M fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications. Use the UA78M for on-card regulation to eliminate noise and distribution problems associated with single-point regulation. The UA78M is also used with power-pass elements to make high-current voltage regulators. The UA78M delivers up to 500mA of outpu.
