Linear Voltage Regulator IC Positive Fixed 1 Output 100mA TO-92-3

UA78L09ACLP General Description

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.
