FUNCTIONAL BLOCK DIAGRAM

GENERAL DESCRIPTION

The TC55 Series is a family of CMOS low dropout positive voltage regulators which can source up to 250mA of current. The extremely low operating current (1.1 A typical) makes this part the ideal choice for battery operated applications and eliminates the need for an additional shutdown mode. The power consumption of the TC55 is 1000 times lower than in bipolar regulators, significantly extending battery life.

The maximum input voltage of 10V combined with the wide output voltage range (1.1V to 6.0V, in 100mV increments) makes this device suitable for a large variety of applications. Other key features include low dropout voltage (380mV typical at 200mA) and excellent line regulation (0.2%/V). The low voltage differential (dropout voltage) also extends battery operating lifetime and permits high currents in small packages when operated with minimum VIN – VOUT differentials.

The circuit also incorporates short-circuit protection to ensure maximum reliability. The TC55 is stable with an output capacitor (ceramic or tantalum) of only 1 F and is available in a tiny SOT-23A package for space critical applications, as well as in a 3-pin SOT-89 and a 3-pin TO92 package.
