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 ⊿VOUT = ±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.
