TCR2EF28,LM(CT

The TCR2EF and TCR2EE series are CMOS single output voltage regulators with an on/off control input, featuring low dropout voltage, low output noise voltage and fast load transient response. These voltage regulators are available in fixed output voltages between 1.0 V and 5.0 V and capable of driving up to 200 mA. They feature overcurrent protection, an Auto-discharge function. The TCR2EF and TCR2EE series has a low dropout voltage of 180 mV (2.5 V output, Iout = 150 mA) with low output noise voltage of 35 μVrms (2.5 V output) and a load transient response of only ΔVout = ±60 mV (Iout = 1 mA ⇔ 150 mA, Cout = 1.0 μF). Thus, the TCR2EF and TCR2EE series are suitable for sensitive power supply such as Analog and RF applications.
