200 mA CMOS Low Drop-Out Regulator with Fast Load Transient Response
The TCR2EF and TCR2EF 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.
