TC2117

800 mA Fixed Low Dropout Positive Regulator

Features

General Description

• Fixed Output Voltages: 1.8V, 2.5V, 3.0V, 3.3V

• Very Low Dropout Voltage

The TC2117 is a fixed, high accuracy (typically ±0.5%)

CMOS low dropout regulator. Designed specifically for

battery operated systems, the TC2117’s CMOS

construction eliminates wasted ground current,

significantly extending battery life. Total supply current

is typically 80 µA at full load (20 to 60 times lower than

in bipolar regulators).

• Rated 800 mA Output Current

• High Output Voltage Accuracy

• Standard or Custom Output Voltages

• Overcurrent and Overtemperature Protection

• Space Saving SOT-223 Package

TC2117 key features include ultra low noise, very low

dropout voltage (typically 450 mV at full load), and fast

response to step changes in load. The TC2117

incorporates both overtemperature and overcurrent

protection. The TC2117 is stable with an output

capacitor of only 1µF and has a maximum output

current of 800 mA. This device is available in 3-Pin

SOT-223, and 3-Pin DDPAK packages.

Applications

• 5V to 3.3V Linear Regulator

• Portable Computers

• Instrumentation

• Battery Operated Systems

• Linear Post-Regulator for SMPS

Package Types

• Core Voltage Supply for FPGAs, PLDs, CPUs,

DSPs
