TC1173 Part Attribute
- Description The TC1173 is a precision output (typically ±0.5%) CMOS low dropout regulator. Total supply current is typically 50 µA at full load (20 to 60 times lower than in bipolar regulators). TC1173 key features include ultra low noise operation (plus optional Bypass input); very low dropout voltage (typically 240 mV at full load) and internal feed-forward compensation for fast response to step changes in load. An error output (ERROR) is asserted when the TC1173 is out-of-regulation (due to a low input voltage or excessive output current). ERROR can be set as a low battery warning or as a processor RESET signal (with the addition of an external RC network). Supply current is reduced to 0.05 µA (typical) and VOUT and ERROR fall to zero when the shutdown input is low. The TC1173 incorporates both over-temperature and over-current protection. The TC1173 is stable with an output capacitor of only 1 µF and has a maximum output current of 300 mA.
