rev. 1.13 - 14 - thermal shutdown thermal shutdown function is included in the r1154 series, if the junction temperature is equal or more than +150c (typ.), the operation of regulator would stop. after that, when the junction temperature is equal or less than +125c (typ.), the operation of regulator would restart. unless the cause of rising temperature would remove, the regulator repeats on and off, and output waveform would be like consecutive pulses. chip enable circuit do not make voltage level of chip enable pin keep floating level, or in between v ih and v il. unless otherwise, output voltage would be unstable or indefinite, or unexpected current would flow internally.
