Standard Variable Output LDO Regulators

300mA Standard Variable Output LDO Regulator

BA3662CP-V5

No.10023EAT05

●Description

The BA3662CP-V5 is low-saturation regulator. The output voltage can be arbitrarily configured using the external resistance. This IC has a built-in over-current protection circuit that prevents the destruction of the IC due to output short circuits and a thermal shutdown circuit that protects the IC from thermal damage due to overloading.

●Features

1) Output Current: 300mA

2) High Output Voltage Precision : ±2%

3) Low saturation with PNP output

4) Built-in over-current protection circuit that prevents the destruction of the IC due to output short circuits

5) Built-in thermal shutdown circuit for protecting the IC from thermal damage due to overloading

6) Built-in over- voltage protection circuit that prevents the destruction of the IC due to power supply surges

7) TO220CP-V5 packaging

●Applications

Audiovisual equipments, FPDs, televisions, personal computers or any other consumer device

●Absolute Maximum Ratings (Ta=25℃)
