TCR2EE series

200 mA CMOS Low Dropout Regulator with Fast Load Transient Response

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.
