Obsolete Device TC55 1 µA Low Dropout Positive Voltage Regulator Features General Description
• Low Dropout Voltage: 120 mV (typ) at 100 mA, The TC55 Series is a collection of CMOS low dropout, 380 mV (typ) at 200 mA positive voltage regulators that can source up to • High Output Current: 250 mA (V 250 mA of current, with an extremely low input-output OUT = 5.0V) • High Accuracy Output Voltage: ±2% (max) voltage differential of 380 mV (typ) at 200 mA. (±1% Semi-Custom Version) The TC55’s low dropout voltage, combined with the low • Low Power Consumption: 1.1 µA (typ) current consumption of only 1.1 µA (typ), makes it ideal • Low Temperature Drift: ±100 ppm/°C (typ) for battery operation. The low voltage differential (drop- out voltage) extends the battery operating lifetime. It • Excellent Line Regulation: 0.2%/V (typ) also permits high currents in small packages when • Package Options: 3-Pin SOT-23A, 3-Pin SOT-89 operated with minimum VIN – VOUT differentials. and 3-Pin TO-92 The circuit also incorporates short-circuit protection to • Short-Circuit Protection ensure maximum reliability. • Standard Output Voltage Options: 1.2V, 1.8V, 2.5V, 3.0V, 3.3V, 5.0V
