TC1070/TC1071/TC1187  
50mA, 100mA and 150mA Adjustable CMOS LDOs with Shutdown  
Features  
General Description  
• Zero Ground Current for Longer Battery Life  
• Adjustable Output Voltage  
The TC1070, TC1071 and TC1187 are adjustable  
LDOs designed to supersede a variety of older (bipolar)  
voltage regulators. Total supply current is typically  
50µA at full load (20 to 60 times lower than in bipolar  
regulators).  
• Very Low Dropout Voltage  
• Choice of 50mA (TC1070), 100mA (TC1071) and  
150mA (TC1187) Output  
The devices’ key features include ultra low noise  
operation, very low dropout voltage – typically 85mV  
(TC1070); 180mV (TC1071); and 270mV (TC1187) at  
full load, and fast response to step changes in load.  
Supply current is reduced to 0.5µA (max) when the  
shutdown input is low. The devices incorporate both  
over-temperature and over-current protection. Output  
voltage is programmed with a simple resistor divider  
• Power-Saving Shutdown Mode  
• Over Current and Over Temperature Protection  
• Space-Saving 5-Pin SOT-23A Package  
• Pin Compatible with Bipolar Regulators  
Applications  
• Battery Operated Systems  
• Portable Computers  
• Medical Instruments  
• Instrumentation  
from V  
to ADJ to GND.  
OUT  
The TC1070, TC1071 and TC1187 are stable with an  
output capacitor of only 1µF and have a maximum  
output current of 50mA, 100mA and 150mA,  
respectively. For higher output versions, please see the
