Low Drop-out Voltage and Low-noise CMOS-LDO Regulators: TCR2EE, TCR2EF Series

Single output 200mA CMOS LDO regulators with a control terminal.
The voltage difference between the input and output features low drop-out characteristics of 180mV (2.5V output, IOUT = 150mA). At the same time, these products achieve 35μVrms (2.5V output) low output noise voltage characteristics and high-speed load transient response characteristics of ΔVOUT = ±60mV (IOUT = 1mA ⇔ 150mA, COUT = 1.0μF).In addition to overcurrent protection, output auto-discharge and other basic functions, these regulators can be recommended for a wide range of applications.
These products are available in the general-purpose SOT-25 (2.9 × 2.8 × 1.1 mm) and SOT-553 (1.6 × 1.6 × 0.55 mm) packages.
