TOSHIBA TCR2EN21,LF(SE

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/SDFN4E (0.8 mm×0.8 mm×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 ΔVout = ±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.
