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 (1.1µA typical)
makes this part the ideal choice for battery operated appli-
cations 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 incre-
ments) 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 1µF 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 TO-
92 package.
