TC595002ECBTR

TC59 Low Dropout, Negative Output Voltage Regulator Features General Description Low Dropout Voltage The TC59 is a low dropout, negative output voltage regulator designed specifically for battery-operated - Typically 120mV 50mA 380mV 100mA systems. Its full CMOS construction eliminates the for -5.0V Output Part wasted ground current typical of bipolar LDOs. This Tight Output Voltage Tolerance: 2% Max reduced supply current significantly extends battery Low Supply Current: 3.5A, Typ life, particularly when the TC59 is operated in dropout. Small Package: 3-Pin SOT-23A Other TC59 key features include low supply current (typically 3.0A) and low dropout operation (typically Applications 120mV at 50mA). The TC59 is packaged in a small Cellular Phones 3-Pin SOT-23A package.
