UA78L10ACLP 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.

J**n 12/02/2021

Works perfectly tested on a dry plant with an Arduino UNO(Values will change if you modify the wires' postion)

F**l 03/21/2021

The fees came broken from the base only on one side, it is immediately visible, only from the factory) in appearance workers, lay all in a pile in one postal package, which is sad, but came whole, so okay. If something is wrong, i will add a tip. It's been three weeks. Thank you!

J**e 11/24/2020

It came, the efficiency did not check

N**s 09/14/2020

Good product for the price. Didn't check with a load but works well from voltage side. Good built quality. Thank you very much. Hoping to buy more in future !
