... Secondary Fixed Output LDO Regulators BA3258HFP, BA33D15HFP, BA33D18HFP ●Description The BA3258HFP, BA33D15HFP, BA33D18HFP are fixed 2-output low-saturation regulators with a voltage accuracy at both outputs of 2%. These series incorporate both overcurrent protection and thermal shutdown (TSD) circuits in order to prevent damage due to output short-circuiting and overloading, respectively. ...

... BA3258HFP,BA33D15HFP,BA33D18HFP ●Notes for use 1) Absolute maximum ratings An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit. If any over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses ...
