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
