TC1189TECTTR Microchip

TC1188/TC1189 MAX8863/64 Pin Compatible, Low Dropout, 120 mA Linear Regulators Features General Description Input Voltage Range: 2.7 V to 6.0 V The TC1188 and TC1189 are fixed output, low dropout linear regulators that operate from a 2.7V to 6.0V input 120 mA Output Current voltage source. The output is capable of delivering up Low Supply Current: 50 A, (typical) to 120 mA while consuming only 50 A of quiescent Low Dropout Voltage: 110 mV, (typical at 100 mA) current. The low dropout voltage, 120 mV, make the Fast Turn-On from Shutdown: 140 sec (typical) TC1188 and TC1189 good choices for battery powered Low Output Noise applications. Integrated over-current and over-temper- Over-Current and Over-Temperature Protection ature protection features provide for a fault tolerant solution. Low Power Shutdown Mode The TC1189 includes an output voltage auto discharge Auto Discharge of Output Capacitor (TC1189) feature. When shutdown, the TC1189 will automatically Applications discharge the output voltage using an internal N-Chan- nel MOSFET switch. Battery Powered Systems Fixed output voltage options for the TC1188/TC1189 Portable Computers are: 1.80V, 2.80V, 2.84V and 3.15V. Both the TC1188 Medical Instruments and TC1189 are available in SOT23-5 packages.
