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 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 (dro...
