An input voltage up to 45 V is regulated to an output voltage of 3.3 V. The component is able to drive loads up to 150 mA. It is short-circuit protected by the implemented current limitation and has an integrated overtemperature shutdown. A reset signal is generated for an output voltage VQ,rt of typically 3.1 V. This threshold can be decreased by an external resistor divider. The power-on reset delay time can be programmed by the external delay capacitor. The additional sense comparator provides an early warning function: Any voltage (e.g. the input voltage) can be monitored, an under- voltage condition is indicated by setting the comparator’s output to low. Additionally, an Enable function permitting enabling/disabling the regulator is also included. In case the regulator is disabled it consumes less current than1µA. |
