TCR2EN series
200 mA CMOS Low Drop-Out Regulator in ultra small package
The TCR2EN series are CMOS general-purpose single-output voltage regulators with an on/off control input, featuring low dropout voltage, low quiescent bias current and fast load transient response. These voltage regulators are available in fixed output voltages between 1.0 V and 3.6 V and capable of driving up to 200 mA. They feature overcurrent protection and an Auto-discharge function.
The TCR2EN series is offered in the ultra small plastic mold package SDFN4 (0.8 mm x 0.8 mm x 0.38 mm). It has a low dropout voltage of 160 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 = ±55 mV ( IOUT = 1 mA⇔150 mA, COUT =1.0 μF).
As small ceramic input and output capacitors can be used with the TCR2EN series, these devices are ideal for portable applications that require high-density board assembly such as cellular phones.

Note: Note1:
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within .
