General Description
The TS9008 is a low dropout, high PSRR, low noise linear regulator with very low quiescent. It can supply
300mA output current with low dropout about 250mV. The Device includes pass element, error amplifier, band-
gap, current-limit and thermal shutdown circuitry. The characteristics of low dropout voltage and less quiescent
current make it good for some critical current application, for example, some battery powered devices. The
typical quiescent current is approximately 30µA. In the shutdown mode, the maximum supply current is less
than 1uA. Built-in current-limit and thermal-shutdown functions prevent any fault condition from IC damage
