General Description The TC2014, TC2015 and TC2185 are high-accuracy (typically ±0.4%) CMOS upgrades for bipolar Low Drop-out Regulators (LDOs), such as the LP2980. Total supply current is typically 55 µA; 20 to 60 times lower than in bipolar regulators. Features • Low Supply Current: 80 µA (Max) • Low Dropout Voltage: 140 mV (Typ.) @ 150 mA • High-Output Voltage Accuracy: ±0.4% (Typ.) • Standard or Custom Output Voltages • Power-Saving Shutdown Mode • Reference Bypass Input for Ultra Low-Noise Operation • Fast Shutdown Response Time: 60 µsec (Typ.) • Overcurrent and Overtemperature Protection • Space-Saving 5-Pin SOT-23A Package • Pin-Compatible Upgrades for Bipolar Regulators • Wide Operating Temperature Range: -40°C to +125°C • Standard Output Voltage Options: \- 1.8V, 2.5V, 2.6V, 2.7V, 2.8V, 2.85V, 3.0V,3.3V, 5.0V Applications • Battery-Operated Systems • Portable Computers • Medical Instruments • Instrumentation • Cellular/GSM/PHS Phones • Linear Post-Regulator for SMPS • Pagers
