Hot-selling and scarce UA78L05AIPK Positive-Voltage Linear Regulators SOT89 spot stock

Product Descriptions

The UA78L series of fixed-voltage linear regulators is  designed for a wide range of applications. The UA78L  series can be used for on-card regulation to eliminate  the noise and distribution problems associated with  single-point regulation. The UA78L can also be  used with power-pass elements to make high-current  voltage regulators. The UA78L series regulators can  deliver up to 100 mA of output current. Additionally,  the UA78L does not need an external capacitor  for stable operation across the load current range.  The internal current-limiting and thermal-shutdown  features of these regulators help protect the device  from overload.

For the legacy chip, the UA78L00C and UA78L00AC  series are characterized for the junction temperature  range of 0°C to +125°C and the UA78L05AI device  is characterized for the operating junction temperature  range of –40°C to +125°C.

For the new chip, the UA78L series is characterized  for the junction temperature range of –40°C to  +125°C.
